Securitron MSS-1G Maximum Security Door Position Switch

Protect your most sensitive openings with the Securitron MSS Maximum Security Switch, a premium high-security door monitoring solution designed to detect and report unauthorized entry attempts. Engineered for versatility, these tamper-resistant switches utilize a unique "mated" magnetic contact system that prevents defeat attempts by foreign magnets—a common vulnerability in standard security contacts. Available with armored cable options, the MSS series provides rugged, reliable status detection for doors, gates, and windows in higher security settings.

The MSS series seamlessly interfaces with your access control and alarm systems, providing real-time remote indication of open/closed status. For advanced egress control, it can be utilized as the initiate signal to XDT delayed egress timers, ensuring your facility remains secure while meeting life-safety requirements. Models like the MSS-1 and MSS-1G feature a hidden anti-tamper output, offering layered protection that triggers an alarm if the switch housing is interfered with. Backed by the industry-leading MagnaCare® lifetime replacement warranty, these switches provide absolute peace of mind for critical security infrastructure.
