Magnasphere MSS-311C 1" Recessed/Concealed Multi-Switch Contact with Switches, Closed Loop, Open Loop, Black

Built for discreet, dependable security monitoring, the Magnasphere MSS-311C recessed magnetic contact delivers reliable, multi-system triggering from a single concealed point. As part of Magnasphere’s MSS-300 series, this 1in diameter recessed/concealed contact is ideal for concealed door and window sensing in alarm, access control and video surveillance applications. The MSS-311C is available in closed-loop or open-loop configurations and offers a standard gap of 3.2in, making it compatible with most alarm panels and monitoring systems.

Unlike fragile reed switches, Magnasphere’s proven switch technology is designed not to break or fuse, lowering maintenance needs and reducing false alarms in high-cycle locations. Hybrid installation options, armored wire leads, and a compact ABS/nylon body make the unit easy to retrofit into storefronts, cabinets, residential doors, and commercial openings. TAA-compliant and US-made, the MSS-311C includes a 1-year limited warranty for procurement confidence.
