Abstract
A two-piece face plate assembly includes a coupling plate which is mounted between the yoke strap of a wiring device and the mounting flange of a wall box. The coupling plate has a central opening for receiving the wiring device and has first and second index pins formed at spaced locations along the longitudinal axis of the coupling plate and in registration alignment with threaded mounting holes on the yoke strap. The coupling plate also has press-fit connectors positioned symmetrically about the central opening. The screwless face plate has a central opening for receiving the wiring device escutcheon and has a corresponding number of complementary press-fit connectors which are aligned for interlocking, press-fit engagement with the coupling plate connectors. The wiring device is mounted onto the wall box by screw fasteners extending through mounting slot openings formed through the yoke strap and in engagement with threaded mounting holes on the wall box. The index pins on the coupling plate project through the threaded retainer holes on the yoke strap, thereby maintaining horizontal and vertical alignment of the face plate with the wiring device. In a multiple wiring device installation, a segmented coupling plate is expandable to accommodate two or more wiring devices.
