GRI TS-20-19 Tamper Switch, SPST-NO with 19"

Protect entry points with a compact, reliable tamper solution designed for professional security systems. The George Risk Industries GRI TS-20-19 tamper switch is a SPST-NO magnetic contact engineered for discreet installation in high-value access control, surveillance and monitoring applications. At just 0.37 inches (3/8") in diameter, it’s the smallest unit in its class, enabling unobtrusive placement on narrow frames where traditional switches won’t fit. Hermetically sealed stainless steel contacts resist sticking and environmental failure, reducing false alarms and maintenance calls. The recessed adjustable plunger accommodates installation gaps from 1/4" to 1/2", while 12" #22 AWG leads and a screw-down flange speed retrofits and new deployments. Built in the US and backed by a lifetime warranty, the TS-20-19 helps integrators and facility managers deliver dependable intrusion detection with lower lifecycle costs. Ideal for commercial door and window tamper detection, retrofitting outdated mechanical switches, or tight-profile security installations—add this trusted magnetic contact to your next surveillance or monitoring project.
