## 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.

## Claims

### Claim 1

In combination with an explosionproof electrical receptacle and switch, said receptacle and switch including a faceplate with a first slot and a second slot therein, one of said slots arranged to receive a male blade contact in either of two mutually perpendicular orientations; an improved terminal block subassembly behind said faceplate and said one slot, comprising:
a terminal block having a front side and a rear side, an elongate and essentially singular piece of electrically conductive metal captivated partially within said terminal block and having a first end protruding from said terminal block front side and a second end protruding from said terminal block rear side,
said first end being slotted longitudinally in two mutually perpendicular planes for receiving said male blade contact in either of said two orientations,
said second end being a switch contact,
and means between said first end and said second end for holding said terminal in said terminal block.
