ABSTRACT:
An electrical switch has a snap action blade with a contact pad. The snap action blade levers between a first configuration at which the contact pad is remote from a stationary contact and a second configuration at which the contact pad abuts the stationary contact. An actuator moves the snap action blade between the first and second configurations. A reset latch has a first position in which a catch coupled to the snap action blade can engage the reset latch to hold the snap action blade in one of the first and second configurations, and has a second position at which such latching does not occur. A manual reset actuator is provided to release the catch from the reset latch. A reset selector determines whether the reset latch is in the first or second position and thus whether the switch is in an automatic reset mode or a manual reset mode.
