George Risk Industries 175-12-W Recessed Dpdt Contact Switch

Product Description

The George Risk Industries 175-12-W is a recessed double-pole double-throw (DPDT) magnetic contact switch designed for security and access control applications. Finished in white, it mounts flush within a door or window frame to remain concealed during normal operation. The DPDT switching configuration provides two independent sets of normally open and normally closed contacts, giving installers flexibility for multi-circuit alarm, access control, or monitoring wiring. This is a single-unit component sold individually and is sized for a 0.5-inch recessed bore. Installation is typically performed by security technicians, electricians, or alarm system integrators.

Recessed DPDT contact switches like the 175-12-W are commonly used in residential and light commercial security installations where a low-profile, concealed sensor is required. Typical applications include door and window frames where surface-mounted hardware is not acceptable. The white finish blends with painted frames and trim, making it well suited for finished interior spaces where aesthetics matter alongside function.

Installation Notes

Installation is typically performed by a licensed electrician or certified security system technician. De-energize and disarm the associated alarm or access control system before beginning work to prevent false alarms or accidental circuit activation. A drill and appropriate bit are required to bore the recessed cavity to the correct diameter in the door or frame. Follow local electrical and security codes, including applicable NEC provisions for low-voltage wiring, when routing and terminating leads.
