ABSTRACT:
A disconnect switch for use in a metal-encapsulated high-voltage switching installation, wherein the switch includes a movable switching pin, a mating contact axially associated therewith, and a cylindrical member arranged in surrounding spaced relationship to the mating contact. The cylindrical member is further formed so as to extend beyond that end face of the mating contact which is in facing relationship with the switching pin, whereby the member projects into the gap between the switching pin and the mating contact when the disconnect switch is in the "off" position and surrounds the switching pin when the switch is in the "on" position.
