ABSTRACT:
An electrical switching device includes a housing, a base attached to the housing, two non-actuated electrical contacts supported in the housing, and an actuator assembly contained within the housing. The actuator assembly includes a movable contact for engaging the non-actuated electrical contact and a wire element formed of a shape memory alloy. Applying an electric current to the wire element causes the actuator to either pivot or rotate the movable contact to either engage or disengage the non-actuated electrical contacts.
