Abstract
An auxiliary switch activation mechanism is provided for use with a circuit breaker having an auxiliary switch and an operating mechanism for opening and closing main electrical contacts. The auxiliary switch activation mechanism includes a lever having a first end removably connectable to the operating mechanism, a second end of said lever removably connectable to the auxiliary switch, and a spring, mechanically coupled to the lever, which imparts a rotational bias on the lever. The lever provides an assisting force to the operating mechanism for opening the main electrical contacts.
