Abstract: A connecting plug for use in conjunction with standard electrical boxes and circuit components such as switches and receptacles. The connecting plug includes a insulator block attached by a grounding screw to the back panel of an electrical box. Rigid contact pins extend outwardly from the insulator block a predetermined distance so that they will be releasably received in the openings in the body sections of the circuit components. Standard wiring extends through a knock-out opening in the box and is connected to the grounding screw and the contact pins. Components are removed from one replaced into the box without disturbing the wiring connections.
