Description
MS2 Wired Door Window Sensor Magnetic NO/NC Switch Home Alarm System
The MS-2 Magnetic Reed Switch (NC/NO) is a surface-mount rectangular contact sensor designed for security and automation systems. It consists of two units: a reed switch with wire terminals and a magnet. This model supports dual wiring modes – NC (Normally Closed) and NO (Normally Open) – offering flexibility for different security system requirements. When the door/window is closed, the magnet keeps the reed contact stable; when opened, the circuit changes state, triggering an alarm or controller.
