George Risk Industries Inc. TS-20 Tamper Switch 3/8 Inch

Product Description

The GEORGE RISK INDUSTRIES INC. TS-20 is a drill-mount tamper switch designed for special application contact installations. The part mounts through a 3/8-inch drilled hole, providing a concealed or flush-mount point-of-entry detection or tamper-indication function. It is used in security, access control, and protective enclosure applications where a discrete, mechanically actuated switch is required. Electricians and security system technicians are the primary installers. The compact drill-mount form factor allows installation in doors, frames, panels, and enclosures where space is limited and a clean finish is needed.

The TS-20 is suited for residential and light commercial security and access control systems. Its 3/8-inch mounting format is compatible with standard drill-bit sizing, making field installation straightforward without specialized tooling. Typical installation scenarios include door and window frames, electrical enclosure panels, and equipment housings where tamper detection or position sensing is required. It falls within the special application contacts product category, indicating suitability for non-standard or purpose-specific switching demands beyond conventional door or window reed switches.

Installation Notes

Installation is typically performed by a licensed electrician or certified security system technician. Disconnect all power to the circuit before removing an existing switch or wiring the new unit. Drill the mounting hole to the specified 3/8-inch diameter and verify the switch actuates correctly at the intended trigger depth before completing final wiring. Follow applicable NEC requirements and local code for low-voltage control wiring.
