Patent attributes
A combination electrical plug, receptacle and switch includes a cylindrical plug portion in which is inserted a cylindrical receptacle portion. The plug portion may be plugged into a conventional electrical socket. An electrical appliance or device may be plugged into the receptacle end. Electrical contacts in the plug portion and the receptacle portion can be made to contact to form a pathway for electrical current by a applying a twisting motion to the receptacle portion. The pathway for the electrical current may be disconnected by twisting the receptacle portion the other way. In this manner, the combination may be conveniently used as an on/off switch for almost any electrical device. Safety features include a way to block twisting of the receptacle end when the switch is in the off position unless the receptacle end is first pulled slightly away from the plug end before twisting it.
