Abstract
Abstract An electrical terminal for a receptacle or other electrical connector and the method of making it. The terminal is preferably a cylindrical screw machine part cross-slotted at one end for receiving a male blade terminal therein in either of two angularly different orientations. When the terminal is used in a combination receptacle and switch, the other end of the terminal, the end opposite the cross-slotted end, may include an integrally formed switch contact for direct interaction with another and mating contact inside the switch portion of the receptacle.
