ABSTRACT OF THE DISCLOSURE A switch which is opened and closed by success- ively depressing a manual operating handle is provided with one spring for separating the switch contacts and a separate spring for closing the switch contacts. In- terrupting capacity is improved without increasing over- all size by utilizing a J-shaped movable contact arm mounted on a pivot located a substantial distance from the movable contact. The closing spring is located ad- jacent to the arcing or interrupter area. A metal shield is positioned to protect the closing spring from hot arcing gases as they exit from the interrupter area. The speed of instantaneous or magnetic tripping is im- proved by providing the against coil with at least one complete current carrying loop.
