GRI TSC-20 3/8" Diameter Recessed Tamper/Plunger Switch, Adjustable, Reed Plunger with Clip Mounted, Closed Loop

Protect sensitive access points with the George Risk Industries TSC-20 recessed plunger switch — a compact, tamper-resistant plunger switch designed for professional security and surveillance installations. The slim 3/8" diameter body fits where standard plungers are too large, delivering discreet monitoring on narrow doors, windows or panels. Installers appreciate the adjustable plunger (1/4" to 1/2") for precise actuation and the clip-mounted design with 12" #22AWG leads for quick, reliable retrofits. Built with hermetically sealed, stainless steel components and plated contacts, the TSC-20 resists sticking, freezing and corrosion to ensure consistent closed-loop (N.O.) performance in alarm, access control and perimeter monitoring applications. George Risk Industries engineered this plunger switch to reduce nuisance trips, simplify alignment and extend service life, lowering maintenance overhead for security integrators and facility managers.
