GRI TS-20-60 3/8" Diameter Recessed Tamper Plunger Switch, Adjustable, Reed Plunger with 60" Leads and without Brackets

For installers who need a compact, dependable tamper solution, the George Risk Industries TS-20-60 recessed tamper plunger switch delivers precise door and window protection with minimal intrusion. This plunger-type tamper switch features a small 3/8" diameter body that fits narrow frames and a nylon flange that resists binding from temperature-driven expansion, making it ideal for perimeter security, access control, and surveillance monitoring systems. The adjustable plunger range (1/4" to 1/2") lets technicians calibrate trip sensitivity for consistent performance, while hermetically sealed reed contacts and a stainless-steel spring provide long-term reliability in high-use environments. With 60" leads standard, the TS-20-60 reduces the need for additional wiring and speeds up installations on retrofit and new-construction projects. UL/ULC approvals and a lifetime warranty offer added assurance for B2B deployments.
