George Risk Industries TS-20-36 SPST-NO Tamper Switch

Add a discrete normally open tamper contact to a physical-security circuit with the George Risk Industries TS-20-36. Its SPST-NO configuration provides one switched circuit path and a normally open contact arrangement for tamper-monitoring applications. Use it where opening, movement, or access to protected equipment needs to be represented as a monitored switch condition within an alarm system. The single-pole, single-throw design is suited to installations that need a simple dedicated tamper point rather than a multi-contact or changeover switch. Typical applications include alarmed enclosures, security cabinets, control panels, protected housings, and equipment cabinets that require a separate tamper circuit. The normally open contact format should match the input logic and supervision method used by the connected alarm panel or monitoring device. TS-20-36 is specifically identified as a tamper switch with an SPST normally open contact configuration. That contact arrangement is the key selection detail for technicians replacing a like-for-like tamper switch or adding a monitored access point to an existing security circuit. Match the switch installation, wiring method, electrical requirements, and required alarm behavior to the connected system before installation.
