Overview
Designed for tamper detection in confined spaces, the George Risk Industries TS-20 recessed plunger switch delivers dependable security monitoring where size and reliability matter. This plunger-style tamper switch features a compact 3/8" diameter and an adjustable plunger travel (1/4" to 1/2") so installers can precisely set actuation for door and window frames, cabinets, and access panels. Built from stainless steel with hermetically sealed, plated contacts, the TS-20 resists sticking, freezing, and corrosion—ensuring continuous operation in harsh environments. The screw-down oval flange secures the switch against vibration and movement, while 12" #22AWG leads simplify wiring to alarm panels, access control systems, and surveillance integrations. Offered as a closed-loop, normally open (N/O) reed plunger, the TS-20 is a straightforward retrofit for older mechanical tampers and an ideal choice for modern intrusion detection and monitoring systems. Backed by George Risk Industries' reputation for durable security components, this switch reduces false alarms and maintenance downtime. Add the TS-20 to your access control, alarm, or surveillance installations—order today.
