SDC MC-4MU Magnetic Switch Single Pole Double Throw, 1.25" x 4.875"

Keep doors under continuous surveillance and preserve access control integrity with the Security Door Controls MC-4MU magnetic switch. This recessed magnetic switch is designed to monitor door position (open/closed) and report state changes quickly to alarm panels, door controllers, or building management systems—strengthening overall security and reducing false alarms. The MC-4MU features a Single Pole Double Throw (SPDT) contact and a low-profile 1.25" x 4.875" footprint for clean edge-of-door installation that remains largely hidden from view. Installation is straightforward: wire the DPS switch into your existing access control or alarm architecture to enable real-time monitoring and event logging. Ideal for commercial, institutional, and multi-tenant facilities, the MC-4MU delivers dependable performance and cost-effective operation while integrating seamlessly into security, surveillance, and monitoring systems. If you need a compact, replaceable sensor (replaces MC-4MV) that supports tight installation tolerances and robust system interoperability, the SDC MC-4MU is a practical choice.
