Claim:
1. A high voltage/high current air break switch, the switch comprising: a support frame; a first electrical terminal electrically insulatively supported by the frame, the first electrical terminal including at least one blade contact; a blade support housing electrically insulatively supported by the frame and disposed apart from the first electrical terminal, the blade support housing being pivotally supported so as to be pivotable about a first axis relative to the frame; a blade supported by the blade support housing so as to be pivotable about a second axis relative to the blade support housing, the blade including a load interrupter between the blade support and a distal end of the blade; and means between a second toggle mechanism and one of the load interrupter contacts for moving one contact and comprising a bistable assembly including bistable links and a translatable latching and a tripping collar, whereby pivotal movement of the blade from an open blade position, in which the blade distal end is spaced apart from the electrical terminal, to a closed blade position, in which the blade distal end enters the electrical terminal and wherein the blade has a longitudinal axis, and the load interrupter has contacts extending along the blade longitudinal axis between the blade support and the distal end of the blade.
