Description of NC Door Window Contact Magnetic Reed Switch for Security
Quick Overview
The NC (Normally Closed) Door Window Contact Magnetic Reed Switch is designed for use in security systems, specifically for monitoring the status of doors and windows. When the magnet is in proximity to the reed switch, the circuit remains closed; it opens when the magnet is moved away, thus triggering a security alert.
How It Works
The reed switch is composed of two thin magnetic reeds sealed within a glass capsule. When the magnet comes close to the reed switch, the magnetic field causes the reeds to attract each other, closing the circuit. When the magnet is moved away, such as when a door or window is opened, the magnetic field weakens, causing the reeds to separate and the circuit to open, thereby signaling a potential intrusion.
