GRI PBF-101T-W 3/4" Diameter Push Button Plunger Switch with Flange and Terminal, 5W, Open Loop, White

Designed for fast, reliable alarm monitoring and retrofit applications, the George Risk Industries PBF-101T-W plunger switch delivers sealed reed performance in a compact, flange-mounted package. The 3/4" diameter PBF flange fits standard 3/4" holes so installers can replace aging mechanical contacts without re-drilling or redesigning door and window assemblies. As an open-loop (N.C.) magnetic contact with Form B reed contacts and a terminal block option, it provides stable, low-wear switching for intrusion detection, access control and perimeter surveillance.

The PBF-101T-W includes an end-of-line resistor option and supports supervisory loops to meet modern alarm panel requirements. UL/ULC certification and a lifetime warranty mean fewer service calls and easier compliance for integrators. Sealed contacts and wired connectivity resist environmental contaminants that commonly cause failures in traditional mechanical switches, increasing uptime for security and monitoring systems.

Choose the George Risk plunger switch when you need a durable, easy-to-install magnetic contact for commercial security, surveillance and access control projects. Order PBF-101T-W today or contact your distributor for volume pricing and technical support.
