George Risk Industries 40RS-12-B Recessed Contact Switch

Product Description

The George Risk Industries 40RS-12-B is a recessed contact switch set designed for use in door, window, and perimeter security applications. This short press-fit style unit installs into a drilled hole in the door frame or stationary surface, eliminating exposed hardware for a clean, tamper-resistant installation. The 3/8-inch barrel diameter makes it compatible with standard recessed contact boring applications. It ships as a complete set with the magnet and contact housing included, and is typically installed by alarm and low-voltage security technicians during new construction or retrofit projects.

This recessed contact set is suited for residential and light commercial security and access control systems. The short body length accommodates thinner door frames and metal or wood surfaces where a standard-length recessed contact would not fit. The press-fit retention method allows for tool-minimal installation without adhesives or additional hardware, making it a practical choice for technicians working in tight frame cavities or predrilled channels.

Installation Notes

Installation is typically performed by licensed low-voltage or alarm technicians in accordance with local security and electrical codes. Power down the associated alarm panel or zone before wiring the contact leads. Press the contact body firmly into the pre-bored hole to seat the press-fit retention ring, and verify the magnet aligns correctly with the contact when the door or window is in the closed position. Do not over-compress the housing during insertion, as this may damage the internal reed switch.
