An electrical switching device (100) includes first and second circuit assemblies (106, 108). Each of the first and second circuit assemblies includes a base terminal (112, 116) and a moveable terminal (110, 114) moveable between an open state and a closed state. The moveable terminal is electrically connected to the base terminal in the closed state. An actuator assembly (130) is electromechanically controlled by a motor (132). The actuator assembly includes a pivot member (134) rotated by the motor that has a post (168) extending outward from a pivot body (160). An actuator (136) is moved by the pivot member and is moveable 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 moveable terminals to the closed state as the actuator is moved from the first position to the second position. The actuator has a pocket (186, 188) with a compression spring (138) received in the pocket. The compression spring extends between a first end (400) and a second end (402). The first end engages the actuator. The second end engages the post. The compression spring provides a force on the actuator to push the moveable terminals toward the base terminals.
