Description
The MS2 Magnetic NC Switch is a surface-mounted magnetic contact sensor designed for door and window security. It consists of two parts: a switch unit containing a reed contact and a magnet unit.
This model operates as NC (Normally Closed), meaning the circuit remains closed when the magnet is aligned with the switch. When the magnet is separated (door/window opens), the circuit breaks, triggering an alarm or control signal.
It is widely used in home security systems, offices, warehouses, automation, and industrial access control.
