Magnasphere MSS-330S Surface Mount Multi-Switch Contact with Armored Cable, Switches, Closed Loop

Secure doors, windows and controlled access points with the Magnasphere MSS-330S surface-mount magnetic contact — engineered for reliable, long-term perimeter monitoring. This Magnasphere magnetic contact uses award-winning solid-state switching (not a reed switch) to deliver consistent closed-loop detection that reduces false trips and maintenance. The integrated armored cable adds a layer of tamper and environmental protection ideal for high-traffic commercial and residential installations. Rated for 30V DC operation and a low 250 mW power draw, the MSS-330S pairs easily with alarm systems, access control panels and surveillance monitoring equipment. Its compact 1" diameter and 0.125" standard gap make it unobtrusive while providing dependable contact performance. Installers benefit from hybrid surface-mount flexibility and multi-switch outputs for triggering multiple independent systems without extra hardware. TAA-compliant and manufactured in the U.S., this contact suits contractors and security integrators who require rugged, code-conscious components. Add the MSS-330S to your next security or access-control deployment for dependable perimeter protection and simplified system integration.
