Magnetic Contact Switch – Wired
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).
- 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.
- 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.
- 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.
Magnetic lock

Magnetic lock
*Capacity: 180 Kg *DC 12 V A magnetic lock, also known as an electromagnetic lock or maglock, is a locking device that uses the principles of electromagnetism to secure a door. Unlike traditional mechanical locks, it has no moving parts. How It Works A magnetic lock consists of two main components:- Electromagnet: This is typically mounted on the door frame. It contains a coil of wire wrapped around a ferromagnetic core.
- Armature Plate: This is a steel plate mounted on the door itself, designed to align with the electromagnet.
- High Security: Magnetic locks can provide a very strong holding force, making them difficult to force open. They are also virtually unpickable, as there are no keyholes or cylinders.
- Durability and Low Maintenance: With no moving parts, magnetic locks experience less wear and tear than traditional locks, leading to greater longevity and reduced maintenance needs.
- Quick Operation: They unlock instantly when power is cut, allowing for quick release, which is beneficial in high-traffic areas or emergencies.
- Remote Operation and Access Control Integration: Magnetic locks can be easily integrated into electronic access control systems, allowing for remote operation, key card/fob access, biometric scanning, and detailed access logging.
- Versatility: They can be installed on various door types, including glass, wood, and metal, and are suitable for both swinging and sliding doors.
- Ease of Installation: Compared to some other electric locks, maglocks can be relatively straightforward to install.
- Constant Power Requirement: Magnetic locks need a continuous power supply to remain locked. This means they are dependent on electricity, and a power outage will result in the door unlocking (fail-safe).
- Cost: While the initial cost of the lock itself might be comparable, the overall installation can be more expensive due to the need for electrical wiring, power supplies, and integration with other security systems.
- Additional Hardware for Safety: To comply with building codes and ensure safe egress, magnetic locks often require additional hardware such as push-to-exit buttons, motion sensors, or panic bars.
- Maintenance of Backup Systems: If battery backups are used to mitigate power outages, these batteries require regular checking and replacement.

-
Importance:This manual release mechanism is essential for emergency access and situations where the automatic system is unavailable.
Mercury Level Switch
Ship or pick up from our office.
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.
- 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.
- 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.
- 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.
Micro Limit Switch
Ship or pick up from our office.
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.
- 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
- 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.

Pedestrian gate electric lock with remote control
* Two remote controls included *DC 12 V pedestrian gate electric lock with a remote control is a security system that allows you to lock and unlock a walk-through gate using an electrical mechanism, typically activated by a remote control. This provides convenience and enhanced security, as you don't need a physical key to open the gate. Here's a breakdown of what it entails: How it Works:- Electric Lock Mechanism: Instead of a traditional manual deadbolt or latch, an electric lock uses an electrical impulse to control a bolt or latch. This impulse can come from a control board connected to various access control devices.
- Remote Control Activation: A key component is the remote control, which sends a wireless signal (radio frequency) to a receiver connected to the lock's control system. When the signal is received and recognized, the lock is instructed to engage (lock) or disengage (unlock).
- Integration with Gate Systems: These locks are often integrated with automatic gate openers or access control systems. When the gate closes, the lock can automatically engage, and when a remote signal is given, it disengages to allow the gate to open.
- Power Source: Electric locks require a power source, typically low voltage (e.g., 12V DC). Many systems include a battery backup to ensure continued operation during power outages.
- Solenoid Locks: These use an electromagnet to extend or retract a bolt, securing or releasing the gate.

Power converter – AC 24 V to DC 12 V
Ship or pick up from our office.
Power converter - AC 24 V to DC 12 V
A power converter - AC 24 V to DC 12 V is a device that transforms alternating current (AC) at 24 volts into direct current (DC) at 12 volts. These are also commonly referred to as AC/DC power adapters or rectifiers. How it Works ⚙️ The conversion process from AC to DC typically involves several key stages:- Step-Down Transformer: The 24V AC input first goes through a transformer. This component reduces the voltage from 24V AC to a lower AC voltage, although not necessarily directly to 12V DC at this stage. It's about getting to a more manageable voltage level for the subsequent steps.
- Rectification: The reduced AC voltage then enters a rectifier circuit, usually made of diodes. Diodes allow current to flow in only one direction, effectively converting the alternating current (which periodically reverses direction) into a pulsating direct current (which flows in one direction but isn't smooth).
- Half-wave rectifiers block half of the AC waveform.
- Full-wave rectifiers (like a bridge rectifier) use both halves of the AC waveform, resulting in a smoother, more efficient conversion.
- Smoothing (Filtering): The pulsating DC output from the rectifier isn't perfectly steady. It has "ripples" or fluctuations. To smooth this out, capacitors are used. These components store electrical energy during the peaks of the waveform and release it during the dips, creating a much more stable and continuous DC voltage.
- Voltage Regulation: Finally, a voltage regulator circuit ensures that the output voltage remains consistently at the desired 12V DC, regardless of minor fluctuations in the input AC voltage or changes in the load connected to the converter. This also helps protect the connected device from voltage spikes or drops.
- CCTV cameras and surveillance systems: Many security cameras operate on 12V DC, and these converters allow them to be powered from a 24V AC power supply (which is often used in larger installations for longer cable runs due to less voltage drop).
- Low-voltage lighting: Converting 24V AC to 12V DC for certain LED lights or other low-voltage lighting systems.
- Industrial control systems: Some industrial equipment or sensors might use 12V DC power while the facility's power supply is 24V AC.
- Automotive accessories (with specific input needs): While most car systems are 12V DC, there might be niche applications where a 24V AC source needs to be converted.
- Various electronic projects and devices that require a stable 12V DC supply from an AC input.
Programmable timer relay
Ship or pick up from our office.
Programmable timer relay
A programmable timer relay is an electronic device that combines the functions of a timer and a relay, allowing users to set specific time delays for switching electrical circuits on or off. Essentially, it acts as an automated switch that operates based on pre-programmed time intervals. This enables the automation of various processes and equipment across a wide range of applications. How it Works Programmable timer relays incorporate internal circuitry (often microcontrollers or digital logic chips) that allow for precise timekeeping and control. Here's a general overview of how they function:- Control Signal: The programmable timer relay receives an input or "trigger" signal, which initiates the timing process. This signal can come from a switch, sensor, or another control device.
- Timing Mechanism: Once the signal is received, the internal timing mechanism begins to count down or up based on the programmed parameters.
- Delay Period: During this delay, the relay's contacts remain in their initial state (either normally open or normally closed).
- Contact Switching: Once the programmed delay period elapses, the relay's contacts change state, either closing to allow current to flow or opening to interrupt it.
- Maintaining State & Resetting: The relay maintains its new state until the input signal is removed, or a reset function is triggered. Programmable relays offer various timing modes, such as:
- On-delay: The relay activates after a set delay once the input signal is applied.
- Off-delay: The relay deactivates after a set delay once the input signal is removed.
- Interval: The relay activates for a set period and then deactivates.
- Cyclic: The relay repeatedly alternates between on and off states for specified durations.
- Industrial Automation: They control the sequencing of machinery, conveyor belts, pumps, and other equipment in manufacturing processes, ensuring precise timing and preventing system overloads.
- Lighting Control: Used in homes, commercial buildings, and street lighting to turn lights on and off at specific times or based on ambient light levels, optimizing energy consumption and security.
- HVAC Systems: Regulate fan operations, compressor cycles, and defrost cycles in heating, ventilation, and air conditioning systems to maintain desired temperatures and reduce energy use.
- Security Systems: Implement delays for door locks, alarm systems, and surveillance cameras, allowing for controlled access and scheduled activation/deactivation.
