Abstract
Disclosed is a wedge shaped actuator device configured to provide separation of spring supported electrical contacts in an electrical switch. The wedge is configured with dual contour sides to maximize transfer of energy from a drive solenoid to the contact carrying springs. Portions of the wedge are relieved to allow for uninhibited movement of the wedge over side surfaces of the contact carrying springs to avoid digging in of any rough materials from the side edges of the spring as may be occasioned due to stamping techniques used to form the springs.
