Abstract
An electrical switching device employs an actuator mechanism formed of a shape memory alloy (SMA). The electrical switching device includes a housing, at least one non-actuated electrical contact 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 an actuator formed of a shape memory alloy (SMA). Application of a first electrical current to the actuator causes the actuator to move the movable contact to either engage or disengage the non-actuated electrical contact.
