Description

These are used to secure an alarm circuit on a door or window. Sold as a pair, one has a magnet inside, the other a reed switch. They have powerful magnets, with self adhesive or screw mount, and screw terminal connections.

Reed Switch contacts: closed when both units are together (ie current flows), and open when apart.

Normally CLOSED (NC) per pair.

Contact operation:

Contacts are closed cicuit when the magnet is alongside the switch. For alarm installation this is denoted as the "normal" state as the door/window is secure and the alarm is armed.


Handy Tip Normally Open & Closed Circuits

This is when the switch contacts are touching in the presence of a switching magnet. The contacts OPEN when the magnet is removed. This is the most common system in alarm circuits.
