GRI PBF-2020-B 3/8" Diameter Push Button Plunger Switch with Flange, 10W, 200VDC, 0.50A, Closed Loop, N/O, A, Brown

Built to secure modern vinyl and custom windows, the George Risk Industries PBF-2020-B plunger switch delivers compact, dependable protection for window security, surveillance, and intrusion monitoring. This 3/8 in plunger switch fits into tight frames so installers can drill a single hole in the frame instead of the sash, reducing installation time and the risk of damaged hardware. The adjustable screw plunger lets technicians fine-tune activation points to prevent nuisance trips, while the closed-loop normally-open contact ensures consistent alarm signaling for monitoring systems. Wiring is simple with 12 in 22AWG leads or optional screw terminals, and the screw-down flange locks the unit securely in place. Rated for low-voltage applications (10W, 200VDC, 0.50A), the brown PBF-2020-B blends discreetly with window frames and integrates easily into access control, alarm panels, and surveillance sensor arrays. Backed by a lifetime warranty and US manufacturing, it’s a cost-effective choice for contractors and security integrators. Add the PBF-2020-B to your next window protection or intrusion detection project to streamline installation and improve system reliability.
