George Risk Industries 2120-12WG-W Recessed Contact Switch

Product Description

The George Risk Industries 2120-12WG-W is a recessed contact switch designed for use in door and window security and sensing applications. This cylindrical, rib-style switch installs into a bored hole in wood-frame construction and makes or breaks a circuit when the door or window opens or closes. The 3/8-inch body diameter suits standard wood-gap installations, and the white finish blends with painted frames and trim. Security installers and alarm technicians use this type of recessed contact as a discreet, surface-clean alternative to surface-mount magnetic contacts.

This recessed contact is intended for wood-gap applications in residential and light commercial settings. It is well suited for hinged doors, casement windows, and similar wood-frame assemblies where a flush-mounted sensor is preferred for aesthetics or code compliance. The switch ships as a single unit and is compatible with standard low-voltage alarm and access control panels that accept normally closed or normally open dry-contact inputs.

Key Features

• 3/8-inch body diameter for standard recessed wood-gap installations
• Rib-style cylindrical housing for secure press-fit retention in bored holes
• White finish for a clean, low-visibility appearance in painted wood frames
• Sold individually, allowing single-point replacement or new installation
• Designed for low-voltage security and access control circuit integration

Compatibility

Designed as an OEM-style recessed contact switch for wood-frame door and window applications in residential and light commercial security systems.

Installation Notes

Installation is typically performed by licensed alarm or low-voltage technicians. Power down or disarm the associated alarm panel before wiring the contact. A standard drill bit sized to the 3/8-inch body diameter is required to bore the mounting hole in the wood frame. Follow NEC low-voltage wiring guidelines and local jurisdiction requirements when routing and terminating signal wire.
