Someone pulls your alarm panel off the backplate and walks away with it. If there's no tamper switch behind it, you just lost your security system for the price of a pry bar. This SPST tamper switch mounts behind your alarm module, bell, or any wall-mounted device. The moment it's pried free, the circuit opens and your alarm fires. 18 mm mounting hole. Normally closed when the button is depressed — so a clean pull triggers the fault. RRP $5.00. Small part, big peace of mind
