George Risk Industries 195-12-B 3/4-Inch Recessed Steel Door Contact

Monitor the open or closed position of a steel door with a recessed magnetic contact that installs in a 3/4-inch opening. The George Risk Industries 195-12-B uses a DPDT switching arrangement, providing two independent contact circuits from one door-position sensor. This configuration suits security and access-control work where separate circuits are needed for alarm reporting, status monitoring, or related control functions. Its recessed format places the sensing hardware within the door and frame installation rather than on exposed surfaces. That makes it appropriate where a lower-profile finished appearance is required and where the door construction calls for a contact intended for steel doors. The 3/4-inch size is a key fitment detail when replacing an existing recessed contact or preparing a new opening. DPDT operation distinguishes this contact from single-circuit door contacts by making two switch paths available at the same sensing point. Use it where the panel, controller, or connected equipment requires separate dry-contact inputs or where one door state must be shared between two circuits. Verify the required mounting opening, door and frame construction, magnet alignment, circuit logic, and electrical ratings before installation. The 195-12-B provides the recessed steel-door contact format for applications that require dual-pole, dual-throw switching.
