  • What's Included
  • For added protection around your home, add a pair of Surface Mount Magnetic Contact Switches to almost any security system. There are 10 pairs of switches included in this kit allowing you to monitor multiple areas around your home. These switches are ideal for any normally open location and will send an alert signal to your security system when it is no longer in a normally open state. Simply mount the magnetic sensors on a door or window so that the two are in contact with each other when the door or window is closed. Slotted mounting holes make it easy to adjust the distance between the magnet and the sensor, with a maximum operational gap of 3/4 inch. Measuring 2.48 inch long and half an inch high, they can be attached with wood or sheet metal screws, sold separately.

    This Normally Open Surface Mount Magnetic Contact Switch is also available individually.

    A Normally Closed Surface Mount Magnetic Contact Switch is also available.

    Other Features
    The switch is waterproof and mounted in a high-impact plastic case. The rhodium plated contacts handle up to 100mA at 100 volts DC and are rated for 50 million openings and closings. It can reliably operate in temperatures between -15&degF and 160&degF. The sensor's maximum operational gap is 3/4 inch.

    Product is exactly as described. Works great for my project. Thanks for the great description. I purchased from Smarthome because their description was clearer than others and I could be sure of getting the correct type of switch.

    So far I have used 4 of the 10 switches in the pack, and 2 have been defective and I've had to replace them already in under a week.
