Contacts offer a simple means of protecting doors, windows and roller shutters. The principle of operation is that one element, (usually fixed to the non moving section), contains a small switch encapsulated in a glass bottle, (called a magnetic reed), and the other elements contain a magnet.
When the magnet is held within the operating gap of the magnetic reed, the switch is held closed and the circuit made. If the magnet is moved outside the operating gap parameters, the circuit opens and an alarm is generated.
