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.

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
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.
- 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.
