Magnetically Actuated Switches
These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away. They’re often used to detect when a door or window opens. Mount the switch in a stationary position, such as a door frame, and mount the magnet to a movable object, such as the door. They do not include a safety relay and cannot be used with safety-guard doors found on machinery.
Switches with a plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
NEMA 6 rated switches are protected from temporary submersion. IP67 rated switches protect against temporary submersion, as well as dust and dirt.

Magnetic Contact Alarm Switches
Wire contacts to an alarm system to alert when doors or windows are opened. Mount the magnet to the door or window and mount the switch to the frame. The alarm will activate when the magnet is pulled away by the opening door or window.
SPDT switches connect to an alarm system and to another device, such as a motion detector.
