Description
Magnetic Reed Switch Door Sensor with Wire MS-1 White (Normal Close)
The MS-1 Magnetic Reed Switch is a surface-mount magnetic contact sensor designed for door and window security applications. It consists of two components – the reed switch (with wire) and the magnet.
When the magnet is close to the switch, the NC (Normally Closed) contact remains closed. If the door or window is opened and the magnet moves away, the circuit breaks, triggering an alarm or control signal.
It is commonly used in intrusion alarms, automation systems, and access control solutions.
