Description
Magnetic Reed Switch Door Sensor with Wire MS-1 White (Normal Close/Normal Open)
The MS-1 Magnetic Reed Switch (NC/NO) is a compact surface-mounted magnetic contact sensor designed for doors, windows, cabinets, and security enclosures. It has two working modes: NC (Normally Closed) and NO (Normally Open), selectable via wiring. The circuit either stays closed or open when the magnet is aligned, and changes state when the door/window opens. This dual-mode functionality makes it highly versatile for intrusion alarms, automation, and access control systems.
