ABSTRACT:
The circuit protector and switch has fixed and movable contacts. The movable contact is provided on the free end of a lever that is made in part from a bi-metallic element. Normally, this lever serves to open or close the contacts as a rocker is moved between "ON" and "OFF" positions. The rocker is biased toward its "OFF" position and has a fixed post that engages the contact lever at least in the "ON" position. The bi-metallic element changes shape to open the contacts in response to an overcurrent/overheat condition.
