This contact is Normally Open (N/O) – The circuit through the contact is complete until the magnet is moved close by. With the magnet in close proximity, the circuit through the contact is broken.

Of the 4 available wires, two carry the signal from the switch while the remaining two function as a tamper loop.

The C series of contacts are designed to have a small form factor and easy push fit installation. They are ideal for use on windows or anywhere a standard 20mm recess will not work.
