ABSTRACT:
An auto accessory electrical adaptor is designed to allow auto electrical accessory items to be operated remotely from a vehicle. Various electrical accessories include a plug for engagement with a cigarette lighter socket in a vehicle, and are thus not conveniently operable remotely therefrom. The present invention provides a cylindrical body formed from a nonconductive plastic material having a central cylindrical bore lined with a metallic sleeve dimensioned for insertion of a standard cigarette lighter auto electrical accessory plug. A cylindrical insulating disk is mounted in the sleeve, adjacent one end of the body and includes a spring metal contact mounted on an outer face. End portions of a pair of insulated wires are connected to the spring metal contact and to the metallic sleeve. Opposite ends of the wires are connected to electrical connectors for engagement with opposite terminals of a battery or a battery charger to provide a DC power supply to an electrical auto accessory item. In a second embodiment of the present invention, the cylindrical body is located in a switch box which includes a switch for selectively disconnecting the power supply from the electrical accessory.
