Abstract
An electrical switching device includes first and second circuit assemblies. Each of the first and second circuit assemblies includes a base terminal and a moveable terminal movable between an open state and a closed state. The movable terminal is electrically connected to the base terminal in the closed state. An actuator assembly is electromechanically controlled by a motor. The actuator assembly includes a pivot member rotated by the motor that has a post extending outward from a pivot body. An actuator is moved by the pivot member and is movable between a first position and a second position. The actuator is operatively coupled to the moveable terminals of the first and second circuit assemblies. The actuator moves the movable terminals to the closed state as the actuator is moved from the first position to the second position. The actuator has a pocket with a compression spring received in the pocket. The compression spring extends between a first end and a second end. The first end engages the actuator. The second end engages the post. The compression spring provides a force on the actuator to push the movable terminals toward the base terminals.
