Abstract

An insulator assembly has a spacer for conducting electrical current from the terminal pad of a bypass switch assembly to the contact of a switch assembly. The insulator assembly has a base. A first switch assembly is connected to the base and has a first switch blade movable between open and closed positions. A second switch assembly is connected to the base and has a second switch blade movable between open and closed positions. A bypass switch assembly is connected to the base and has a bypass switch blade movable between open and closed positions. The bypass switch assembly has a first conductor electrically connected to the bypass switch blade when the bypass switch blade is in the closed position. A support member is connected to the first conductor and has an opening. A second conductor is electrically connected to the first switch blade when the first switch blade is in the closed position. A spacer is disposed in the support member opening to transfer electrical current from the first conductor to the second conductor. The spacer has a first surface in electrical contact with the first conductor and has a second surface in electrical contact with the second conductor.

Claims
