ABSTRACT:
The present invention, in one form, is an apparatus for interrupting current flow between a fixed contact and a movable contact. An insulating partition has an aperture, and the fixed contact and movable contact are on opposite sides of the partition aperture. The movable contact is coupled to a first movable electrically insulating member, and the first insulating member is coupled to a second movable insulating member, each member being adjacent the partition. A third movable insulating member is coupled to the partition opposite the first and second insulating members with respect to the aperture. The third insulating member extends partially over the aperture. The first and second member are coupled to the movable contact so that when the movable contact is moved to an open current-interrupting position, the second insulating member covers the aperture, and the first insulating member engages the third insulating member and covers both the second insulating member and the aperture.
