ABSTRACT:
An electrical switch has a snap action blade with a contact pad. The snap action blade toggles between a first configuration at which the contact pad abuts a stationary contact and a second configuration at which the contact pad is remote from the stationary contact. An actuator moves the snap action blade between the first and second configurations. A reset spring has a first position which biases the movable contact into one of the first and second configurations, and has a second position at which that biasing does not occur. A reset selector acts to determine whether the reset spring is in the first or second position. A manual reset actuator is provided to move the snap action blade into the one of the first and second configurations when the reset spring is in the second position. Operation of the reset selector selects whether the switch is in an automatic reset mode or a manual reset mode.
