ABSTRACT:
A plastic switch actuator is fitted with a spring so as to impart sliding and rocking motion to a movable contact by virtue of direct engagement between spring and element. The actuator has a depending integral portion received in an opening of the element but it is the spring which keeps the element in contact with the fixed switch contacts. Other embodiments provide for a switch actuator having a movable contact element capable of retention in a "center-off" position wherein the movable contact is held in a stable "off" position in contact with only the center contact. The movable element is readily moved by the depending actuator portion through joint action by the actuator and the spring provided on said actuator.
