How to distinguish between Recessed NO Magnetic Window and Recessed NC Magnetic Window

The Recessed Magnetic Window is composed of a reed switch and a magnet.

1. The reed switch is normally openNO. When there is no magnet approaching, two small pieces of magnetic reed are disconnected; when

the magnet is close, two small pieces of magnetic reed are connected. This is a normally open Recessed Magnetic WindowNO.

Switch Pattern:normally open (NO), when the door(magnet) closed, the switch keeps connecting



 

2. The reed switch is normally closedNC.  Two small pieces of magnetic reed are connected when there is no magnet approaching.

Two magnets are separated when a magnet approaches. This is a normally closed Recessed Magnetic Window(NC)

Switch Pattern:normally closed (NC), when the door closed, the switch are separated.
