A hinge pin is described for an appliance door which combines the functions of a plug-in, mechanical hinge pin and bearing member for the door, adaptable for either right-hand or left-hand opening doors, with that of an electrical connector to bring power into the door without the need of a separate, external service loop to the door. A frame-mounted mating receptacle is provided in the combination for sliding engagement of the hinge pin and plug with the appliance in two embodiments permitting a "universal", side-by-side mounting of two or more doors. Electrical connectors are included for engagement with the hinge pin and plug combination, both at the appliance frame and within the door.
