  • What's Included
  • Use this Garage Door Contact Switch on garage doors, roll-up doors and other doors or gates where it may be difficult to mount regular magnetic contacts. Smaller magnetic switches have a small operating gap where the contact and magnet must be within half an inch for reliable operation. While those switches are fine for most doors and windows in a home, they just won't cut it for larger doors. These contacts can be as far as 2 inches apart and still operate. These Garage Door Contacts for Closed Circuits are used for systems that expect a closed circuit when the magnet and sensor are together. When the magnet and sensor separate, the circuit opens. This set is commonly used with security systems.

    This sensor mounts to the floor and is made of a heavy duty polished aluminum die-cast housing. The contact switch is completely sealed with in this housing. On your door or gate, mount the magnet to complete the system. It is mounted on an adjustable L-bracket and is easily adjustable horizontally and vertically. A flexible 24 inch stainless armored cable protects the wires as they run along the ground.

    Keep Failing Review by Mark
    Keep Failing

    They work fine under normal conditions but I've had 6 of them fail due to lightning storms. I even put transient suppressor diodes across them but nearby strikes still cause them to fail. Failure mode is stuck in NC position so you're not even aware when the failure occurs as the circuit looks normal. Contacted manufacturer but they gave no response as to a solution.

    Failed after 8 years

    Have 4 of these, one failed closed after 8 years service on residential garage door. Nice looking product but expected longer life, I will replace all 4 due to reliability concerns.

    Review of 7455

    Very solid sensor switch that works great. I installed it with an io linc to monitor a garage door. I purchased the two items separately rather than the io linc garage door kit. The lead wires could be a little longer, but I added about 1.5 feet of extra 22g wire to get it to reach my io linc.
