Nascom N1178CTSHK/ST Recessed 3/4" Stubby PTF Closed Loop Switch

Get reliable, low-profile security monitoring for doors and windows where space is limited. The Nascom N1178CTSHK/ST recessed 3/4-inch stubby magnetic contact delivers discreet closed-loop detection that integrates seamlessly into commercial and residential alarm systems. Its PTF closed-loop switch design ensures consistent contact state reporting and resists false alarms from slight misalignment, while the compact recessed form factor hides the sensor for a clean, professional finish. Built with RX/NEO Shark-compatible technology, this magnetic contact works well with a wide range of control panels and receivers used in security, surveillance, and monitoring installations. Technicians appreciate the stubby 3/4" design for tight jambs and frames, and facility managers value the reduced visibility and dependable performance that lower maintenance and service callbacks. Ideal for retrofit projects and new security builds, the Nascom N1178CTSHK/ST provides a durable, easy-to-install solution for perimeter sensing and access monitoring. Add this magnetic contact to your next alarm or surveillance deployment to improve detection reliability and preserve aesthetics.
