Abstract
Abstract An electrical connector is provided for use with hand tools or the like that are normally joined to drop cords. The connector is placed between the drop cord and the electrical supply cord of the tool and allows the supply cord to be turned in a continuous clockwise or counterclockwise direction without rotation of the drop cord or twisting of the supply cord. The connector of the invention includes a pair of opposing plates which are rotatably connected whereby during rotation electrical current passes through both plates without interruption thus allowing the tool to be continuously used during an eight hour work period with the tool being directed in the same circular motion without concern of twisting or effective shortening of the supply cord.
