14 ABSTRACT OF THE DISCLOSURE An electrical switch for use in alternating current circuits is constructed to provide slow contact separation and positive switch action. A pivotal mount- ed operating handle accepts a pivot pin at one end of a link member. A pivot pin at the other end of the link member fits into a brush lifter. Angular motion of the operating handle produces rectilinear motion in the brush lifter which results in opening and closing the switch contacts. A unique arc shield which encircles one out of each pair of contacts, protects the switch mechanism from destructive effects of contact arcing.
