Micro Limit Switch

A micro limit switch, often simply called a micro switch, is a type of electrical switch that’s characterized by its small size and the precise, rapid action it takes when a minimal amount of force is applied to its actuator. It’s designed to detect the presence or position of an object or the end of a mechanical movement.

These switches are known for their:

High sensitivity: They require very little force to activate.
Rapid response: The internal contacts “snap” open or closed very quickly, regardless of how slowly the actuator is pressed. This snap-action mechanism helps to reduce arcing and extends the switch’s lifespan.
Reliability: They are built to withstand millions of operations, making them durable for long-term use.
Compact size: Their small footprint allows them to be used in applications where space is limited.

How it Works

A micro switch typically consists of:

Actuator: This is the external part that an object or mechanical component presses against. It can be a button, a lever (with or without a roller), a plunger, or other forms.
Internal spring mechanism: This provides the “snap-action.” When the actuator is pressed to a certain point (the “trip point”), the spring mechanism rapidly moves the contacts.
Contacts: These are the electrical components that open or close the circuit. Micro switches usually have three terminals:
- Common (C): The input terminal.
- Normally Open (NO): This contact is open (no current flows) when the switch is unactivated and closes when the switch is actuated.
- Normally Closed (NC): This contact is closed (current flows) when the switch is unactivated and opens when the switch is actuated

When the actuator is pressed, it reaches a specific “operating point” where the contacts change their state (either from NO to closed, or NC to open). When the pressure is removed, the actuator returns to its original position, and the contacts revert to their normal state.

Applications

Micro limit switches are incredibly versatile and found in a vast array of devices and systems due to their precision and reliability. Some common applications include:

Household Appliances:
- Microwave ovens: To detect if the door is closed before operating.
- Washing machines: For door interlocks and water level detection.
- Refrigerators: To turn the light on/off when the door opens/closes.
- Printers: To detect paper jams or the position of paper.
Automotive Industry:
- Car doors: To detect if a door is open or closed (e.g., for interior lights or security systems).
- Brake pedals: To activate brake lights.
- Seat belt mechanisms: To detect if a seat belt is fastened.
Industrial Automation:
- Conveyor systems: To detect the presence of items or the end of travel for a belt.
- Robotic arms: For precise positioning and limit detection of movement.
- Machine safety guards: To ensure guards are correctly positioned before machinery operates.
- Elevators and hoists: To prevent over-travel and ensure proper door operation.
Consumer Electronics:
- Computer mice and keyboards: For button clicks.
- Vending machines: For coin detection or jam detection.
Medical Equipment:
- In various diagnostic tools and surgical instruments for precise control.

Types of Micro Limit Switches

Micro limit switches come in various configurations, primarily differing by their actuator type, which dictates how they interact with the mechanical force. Common actuator types include:

Pin Plunger: A simple button-like plunger that is directly pressed.
Roller Lever: Features a lever with a roller at the end, ideal for applications with sliding or rotating components.
Hinge Lever: A simple lever arm that pivots to actuate the switch.
Flexible Roller: Similar to a roller lever, but with a more flexible arm to accommodate irregular surfaces or wider ranges of motion.
Spring Plunger: A plunger supported by a spring, allowing for a certain degree of “overtravel” beyond the actuation point without damaging the switch.

Other variations include sealed micro switches for harsh environments (resistant to dust and moisture) and subminiature types for extremely compact applications.

Sliding gate operator limit sensor -Spring

A sliding gate operator limit sensor with a spring mechanism (also known as a mechanical limit switch or spring limit switch) is a common type of sensor used in automatic sliding gate systems to define the gate's fully open and fully closed positions. Here's how it works and what its characteristics are: Purpose of a Limit Sensor: For any automatic gate operator, the system needs to know exactly when the gate has reached its desired open and closed positions. This is crucial for:

Stopping the Motor: Preventing the motor from continuing to run once the gate has reached its limit, which would otherwise cause damage to the gate, the motor, or the track.
Safety: Ensuring the gate stops precisely where it should, preventing it from hitting obstacles or over-extending.
Proper Operation: Allowing for features like auto-closing, pedestrian mode, and proper synchronization if it's a dual-gate system.

How the Spring Mechanism Works:

Components: A spring limit switch typically consists of:
- A microswitch (an electrical switch that requires very little force to operate).
- A spring-loaded lever, arm, or plunger connected to the microswitch.
- A mounting bracket to attach it to the gate operator or gate frame.
Mounting: The spring limit switch is usually positioned on the gate operator itself, or on a bracket near the motor.
Interaction with the Gate:
- On the sliding gate itself, usually along the gear rack or a specific part of the gate frame, two small "stop" tabs or flags are installed – one for the open limit and one for the close limit.
- As the gate moves towards its fully open or fully closed position, one of these tabs/flags will physically contact and push against the spring-loaded lever/plunger of the limit switch.
- This physical contact compresses the spring and activates the microswitch.
Signal to Control Board: When the microswitch is activated, it sends an electrical signal to the gate operator's main control board.
Motor Stop: Upon receiving this signal, the control board immediately cuts power to the motor, stopping the gate precisely at that determined limit.

Key Characteristics and Considerations:

Physical Contact: The defining feature is that it relies on direct physical contact and force to activate the switch.
Reliability: Generally reliable as they are a simple mechanical system.
Durability: Made to withstand repeated physical contact. However, over time, the spring can wear out, lose tension, or the switch itself can be damaged by repeated impacts or debris.
Adjustability: The position of the "stop" tabs on the gate can be adjusted to fine-tune the exact open and closed positions of the gate.
Maintenance: May require periodic checks to ensure the spring is intact, the switch is clean, and the "stop" tabs are securely in place and correctly positioned. They can be susceptible to damage from impacts (e.g., if a child's toy or a pet gets in the way of the stop tab).
Compared to Magnetic Limit Switches:
- Magnetic Limit Switches: These are more common in newer and higher-end gate operators (like many BFT Deimos "Ultra" models). They use magnets attached to the gate and magnetic sensors (reed switches or Hall effect sensors) on the operator. They offer a "contactless" operation, which generally leads to less wear and tear, greater precision, and less susceptibility to environmental debris or physical impact damage.
- Spring/Mechanical Limit Switches: Are typically more cost-effective and simpler in design. They are still widely used, especially in more budget-friendly or older gate operator models.

Where you'd find them: You would find spring mechanism limit sensors on many brands and models of sliding gate operators, particularly those that use a gear rack system. When looking for replacement parts or considering a new gate operator in Vancouver, BC, it's important to identify whether the system uses mechanical (spring) or magnetic limit switches, as they are not interchangeable. Suppliers like Royal Gates (Royal Electronic Technology Center Co.) would carry these as spare parts for compatible gate operators.

Infrared PIR Motion Sensor Switch

Accessories

$26.55

Infrared PIR Motion Sensor Switch

An Infrared PIR Motion Sensor Switch is an electronic device that detects movement by sensing changes in infrared (IR) radiation in its field of view. "PIR" stands for Passive Infrared, meaning it doesn't emit any energy itself but rather passively monitors the infrared radiation given off by objects. 🌡️ How it Works At the core of a PIR sensor is a pyroelectric sensor, which is sensitive to heat (infrared radiation). Most PIR sensors have two halves, or "slots," wired in a differential arrangement. Here's a simplified breakdown of its operation:

Idle State: When there's no movement, both halves of the sensor detect the same amount of ambient infrared radiation from the surroundings.
Motion Detection: When a warm object, like a human or animal, moves into the sensor's field of view, it first intercepts one half of the sensor, creating a temporary difference in the infrared radiation detected by the two halves. This difference generates a voltage pulse.
Signal Processing: The sensor's circuitry processes this voltage pulse. If the change is significant and matches the pattern of a moving heat source, the sensor triggers an output signal.
Fresnel Lens: A key component of a PIR sensor is the Fresnel lens . This specially designed plastic lens focuses infrared radiation from different angles onto the pyroelectric sensor, effectively dividing the detection area into multiple sensitive zones. This allows the sensor to have a wider field of view and detect movement more effectively.

Since PIR sensors only detect changes in infrared radiation, they are primarily sensitive to movement across their field of view rather than motion directly towards or away from them. They also cannot "see" through objects that block heat emissions. Applications PIR motion sensor switches are widely used in various applications due to their affordability, energy efficiency, and reliability:

Automatic Lighting Control: This is one of the most common applications. PIR sensors turn lights on when someone enters a room, hallway, or outdoor area and turn them off after a set period of no motion, saving energy.
Security Systems: They are integral to security alarms, detecting intruders and triggering alerts or security cameras.
Smart Home Systems: PIR sensors play a role in smart homes for automating various functions, from lighting and HVAC systems to controlling appliances based on occupancy.
Automatic Doors: In public buildings, they detect approaching individuals to automatically open doors.
Energy Management: By ensuring that lights, HVAC, and other devices only operate when an area is occupied, PIR sensors contribute significantly to energy savings in residential and commercial settings.
Wildlife Tracking and Research: Researchers use them to monitor animal movements without disturbance.

Diode 1N4007

The 1N4007 is a very common and versatile silicon rectifier diode. It's part of the 1N400x series of general-purpose diodes, with the "7" indicating its specific voltage rating. Key Characteristics

Rectifier Diode: Its primary function is to convert alternating current (AC) into pulsating direct current (DC) by allowing current to flow in only one direction.
High Reverse Voltage Rating: The 1N4007 can withstand a peak repetitive reverse voltage ( $V_{RRM}$ ) of 1000V. This makes it suitable for high-voltage applications.
Average Forward Current: It can handle an average forward current ( $I_{F}$ ) of 1 Ampere (1A).
Forward Voltage Drop: When conducting in the forward direction, it has a relatively low forward voltage drop ( $V_{F}$ ) of approximately 0.7V to 1.1V. This voltage drop represents the power lost within the diode.
Surge Current Capability: It can handle a non-repetitive peak surge current ( $I_{FSM}$ ) of up to 30A for short durations, which is useful for handling initial power-on surges.
Package Type: It typically comes in a DO-41 axial-lead package, which is a small, cylindrical plastic package with leads on both ends.
Operating Temperature Range: It operates reliably over a wide temperature range, typically from -55°C to +175°C.

How it Works Like all diodes, the 1N4007 is a PN-junction device. It consists of a P-type semiconductor and an N-type semiconductor joined together.

Forward Bias: When a positive voltage is applied to the anode (P-side) and a negative voltage to the cathode (N-side), the diode is forward-biased. If the applied voltage exceeds the forward voltage drop (around 0.7V for silicon diodes), the diode conducts, allowing current to flow from anode to cathode.
Reverse Bias: When a negative voltage is applied to the anode and a positive voltage to the cathode, the diode is reverse-biased. In this state, the diode acts like an open switch, blocking current flow. The 1N4007 is designed to withstand up to 1000V in this reverse-biased state before breaking down.

Common Applications The 1N4007's robust characteristics make it popular in a wide range of electronic circuits, including:

Rectifier Circuits:
- Half-wave and Full-wave Rectifiers: Essential for converting AC power from the mains (like in household appliances) to DC power for electronic devices.
- Bridge Rectifiers: Used to convert the entire AC waveform into pulsating DC, achieving more efficient rectification.
Power Supplies: Used for rectifying the AC input in power supply units to provide DC voltage to various components.
Voltage Protection:
- Reverse Polarity Protection: Prevents damage to circuits if the power supply is connected with incorrect polarity.
- Freewheeling Diodes (Flyback Diodes): Protect sensitive components from voltage spikes generated by inductive loads (like relays, motors, and solenoids) when their magnetic field collapses.
- Voltage Spike Suppression: Helps to suppress transient voltage spikes that can occur due to switching events or lightning, safeguarding delicate electronics.
Inverters and Converters: Used in various power conversion circuits.
Current Flow Regulation: Can be used in simple current limiting or flow control applications.

Due to its high reverse voltage rating, the 1N4007 is often a go-to choice when a general-purpose rectifier diode is needed, especially in circuits that might experience higher voltages.

Mercury Level Switch

Accessories

Mercury Level Switch

A mercury level switch is a type of electrical switch that uses a small amount of liquid mercury to open or close an electrical circuit based on its position or the level of a liquid. Essentially, the mercury acts as a conductive bridge between electrical contacts. How it Works The core component of a mercury level switch is a sealed glass or metal capsule containing one or more electrical contacts and a small, free-moving drop of mercury. When the switch or the liquid it's monitoring changes its tilt or level:

Tilt Switches: Gravity pulls the mercury to the lowest point within the capsule. If the tilt is sufficient, the mercury will flow to connect two or more contacts, completing an electrical circuit. Tilting it in the opposite direction moves the mercury away, breaking the circuit.
Float Switches: In liquid level applications, the mercury switch is often integrated with a float mechanism. As the liquid level rises or falls, the float moves, which in turn tilts the mercury switch, causing the mercury to connect or disconnect the contacts.
Displacement Switches: Some designs use a "plunger" that dips into a pool of mercury, raising the mercury level to contact an electrode and complete the circuit.

Applications Historically, mercury level switches were used in a wide range of applications due to their reliability and the non-eroding nature of mercury contacts. These included:

Thermostats: In older thermostats, they controlled heating and cooling systems.
Sump Pumps: Used to automatically turn on the pump when water levels rise.
Appliances: Found in washing machines (for lid switches and load balancing), chest freezers (for lid lights), and some gas appliances like ovens and water heaters (as flame sensors).
Automotive Industry: Previously used for trunk lid lights, ride control, and anti-lock braking systems.
Industrial Settings: Utilized in liquid level control and safety systems.
Roll Sensing/Tip-over Warnings: For construction equipment or other vehicles operating on uneven terrain.

Advantages and Disadvantages Advantages:

Durability and Reliability: The sealed contacts prevent oxidation, leading to a long lifespan.
Quiet Operation: No abrupt snapping of contacts.
No Contact Erosion: Mercury's liquid nature prevents the wear and tear seen in mechanical contacts.
Spark-Free: They don't produce sparks when making or breaking circuits, making them suitable for hazardous environments.

Disadvantages:

Toxicity of Mercury: This is the primary and most significant disadvantage. Mercury is a highly toxic substance, posing serious environmental and health risks if released.
Environmental Concerns: Improper disposal of mercury switches can lead to widespread contamination. Due to these concerns, the use of mercury switches has been largely phased out in many applications, especially in new products.
Sensitivity to Gravity/Orientation: While an advantage for tilt sensing, it makes them unsuitable for portable or mobile devices where orientation changes or vibrations could cause false readings.
Limited Functionality: Most mercury switches provide only a simple on/off function.

Due to the toxicity of mercury, many applications that once relied on mercury switches have transitioned to safer, alternative technologies such as solid-state sensors, optical sensors, or mechanical float switches.

Magnetic Contact Switch – Wired

Accessories

$9.20

Ship or pick up from our office.

Magnetic Contact Switch

A magnetic contact switch, often simply called a magnetic contact or door/window sensor, is a simple yet highly effective security device that detects when a door, window, gate, or any movable barrier is opened or closed. How it Works: It consists of two main parts:

The Sensor Unit (with a Reed Switch): This part contains a reed switch. A reed switch is a small, hermetically sealed (airtight) glass capsule with two tiny, flexible magnetic metal reeds (or contacts) inside. These reeds are usually made of a ferromagnetic material. This sensor unit is typically mounted on the stationary part of the opening (e.g., the door frame, window frame, or gate post).
The Magnet Unit: This part contains a small, permanent magnet. This unit is mounted on the moving part of the opening (e.g., the door itself, the window sash, or the gate panel).

The Operational Principle:

Closed Position (Circuit Complete): When the door/window/gate is closed, the magnet unit is in very close proximity to the sensor unit. The magnetic field from the permanent magnet pulls the two tiny reeds inside the glass capsule together, causing them to make electrical contact. This completes an electrical circuit, indicating that the opening is secured.
- Many common contacts are "Normally Open" (NO), meaning the circuit is open when the magnet is away and closes when the magnet is near.
- Some are "Normally Closed" (NC), meaning the circuit is closed when the magnet is near and opens when the magnet is away. This is very common in security systems, as an "open" circuit triggers an alarm.
Opened Position (Circuit Broken/Changed): When the door/window/gate is opened, the magnet moves away from the reed switch. As the magnetic field weakens, the reeds spring back to their original position, breaking the electrical contact. This change in the circuit (from closed to open, or open to closed, depending on the type) signals the connected system (e.g., a car alarm, home security system, or gate control panel) that the opening has occurred.

Common Applications:

Security Systems (Homes, Businesses, Vehicles): This is the most prevalent use. Magnetic contacts are placed on:
- Doors and Windows: To detect unauthorized entry. When a door or window is opened, it triggers the alarm.
- Garage Doors/Overhead Doors: Larger, more robust magnetic contacts are used for garage doors.
- Gates: Used on pedestrian gates or even main driveway gates (sometimes in conjunction with the gate opener's own limit switches) to monitor their open/closed status for security purposes.
- Safes and Vaults: To detect if they have been opened.
- Vehicle Doors/Trunks/Hoods: While vehicles have internal sensors, magnetic contacts can be added for enhanced security on specific compartments or custom modifications.
Access Control Systems: To monitor entry and exit points, log access events, or control other devices based on door status.
Automation Systems: To trigger actions based on the status of a movable part. Examples include:
- Turning lights on/off when a door opens.
- Indicating when a cabinet door is ajar.
- Position sensing in industrial machinery.
Appliance Safety: Some appliances use magnetic contacts to ensure a lid is closed or a guard is in place before operation.

Types:

Surface Mount: Most common, easily screwed or adhered to the surface of the frame and door.
Recessed/Flush Mount: Designed to be drilled into the frame and door for a more discreet, hidden installation.
Heavy Duty/Overhead Door Contacts: Larger and more rugged, built for the heavier use and larger gaps often found with garage or industrial doors.
Wired vs. Wireless:
- Wired: Physically connected to the alarm panel via wires, offering high reliability.
- Wireless: Contain a small battery and a radio transmitter to send signals wirelessly to the alarm panel, offering easier installation.

In Vancouver, BC, magnetic contact switches are a common product found at security system suppliers, electrical wholesalers, and businesses that install residential and commercial security systems, including companies like Royal Gates if they offer security integrations for their gate systems.

Ship or pick up from our office.

Garage Door Opener Remote Control

A garage door opener remote control is a small, handheld device that uses radio frequency (RF) signals to wirelessly communicate with your garage door opener system. Essentially, it's a transmitter that sends a unique code to a receiver built into your garage door motor unit, telling it to open or close the garage door. Here's a breakdown of how it works and its key features: Functionality:

Signal Transmission: When you press a button on the remote, it sends a radio frequency signal containing a specific code.
Signal Reception: The garage door opener has a receiver that constantly "listens" for these signals.
Code Matching: If the received code matches the opener's stored code, the receiver activates the motor.
Motor Activation: The motor then powers a drive mechanism (chain, belt, screw, or direct drive) that moves the garage door up or down.

Key Technologies and Features:

Radio Frequency (RF) Communication: Most remotes operate using RF signals (commonly 315 MHz or 390 MHz), allowing them to work from a distance and even through walls.
Fixed Code Technology (Older): Early remotes used a fixed code that was sent every time. This was less secure as the signal could be easily intercepted and duplicated.
Rolling Code Technology (Modern): To improve security, modern remotes use rolling code technology. The code changes every time you press the button, making it extremely difficult for unauthorized individuals to "grab" and reuse the code. Brands like LiftMaster (Security+ / Security+ 2.0) and Genie (Intellicode®) use their own versions of this.
Dip Switches (Older): Some older remotes used physical dip switches that needed to be manually set to match the receiver's code.
Wi-Fi and Smart Home Integration: Many newer garage door openers feature built-in Wi-Fi, allowing you to control your garage door from anywhere using a smartphone app (e.g., MyQ for LiftMaster/Chamberlain, Aladdin Connect for Genie). These apps often offer additional features like real-time notifications, scheduling, and access history.
Multi-Button Remotes: Some remotes have multiple buttons, allowing you to control several garage doors or even other devices like lights.
Universal Remotes: These are programmable remotes designed to be compatible with various brands and models of garage door openers, reducing the need for multiple remotes.

Types of Remote Controls:

Standard Remotes: Basic remotes with one or more buttons to operate the garage door.
Visor Remotes: Larger remotes designed to clip onto your car's sun visor for easy access while driving.
Keychain Remotes: Small, compact remotes that can be attached to your keyring for portability.
Keypad Remotes: Mounted outside your garage door, these allow you to enter a numerical code to open the door, useful for keyless entry.

In essence, a garage door opener remote control provides convenience and security, allowing you to operate your garage door with a simple press of a button from inside your vehicle or as you approach your home.
