GRI TS-20-36 3/8" Diameter Recessed Tamper Plunger Switch, Adjustable, Reed Plunger with 36" Leads and without Brackets

Protect narrow-frame doors and windows with a compact, professional-grade tamper solution. The George Risk Industries TS-20-36 recessed tamper plunger switch is engineered for security and monitoring applications where space is limited but reliability is not negotiable. Its 3/8" diameter housing fits into tight gaps while the adjustable plunger (1/4"–1/2") allows precise actuation to minimize nuisance alarms during everyday use.

Built around a hermetically sealed reed contact and a stainless steel spring, the TS-20-36 resists corrosion and mechanical wear—delivering consistent operation for surveillance and intrusion detection systems. The standard 36" leads simplify wiring to control panels, and the nylon construction prevents binding from thermal expansion or contraction. UL/ULC approvals and a lifetime warranty give installers and facilities managers the confidence needed for critical security deployments.

Ideal for alarm panels, access control, and monitoring of doors and windows in commercial, institutional, and residential projects. Specify the TS-20-36 for compact, dependable tamper detection—order now or contact us for custom lead lengths and supervisory loop options.
