Abstract

The present invention relates to a rotary switch. In particular, the rotary switch includes a main contactor having a main contact carrier and a main cam, a shaft rotatably journaled in the main contactor and extending axially through the main contactor, and an auxiliary contactor. When the switch is rotated from the ON position to the OFF position, the shaft rotates to break open auxiliary contacts before main contacts break open upon further rotation of the shaft.
