Are you still worried about theft prevention? The door magnetic switch can help you detect whether doors, windows, drawers, etc. have been opened or moved.

Door Magnetic contact switches are low-current devices that send a signal to an alarm or a supervised monitoring system when an armed door is opened. They help keep buildings and controlled-access areas secure.

Magnetic alarm contacts are mainly composed of two parts: a switch and a magnet. The switch part has a magnetic spring switch that is connected by a lead wire and packaged into a fixed shape; The magnet with corresponding magnetic field strength is encapsulated in a plastic or alloy shell. When the two are separated or close to a certain distance, it causes the switch to open and induce a change in the position of th problem.
