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 enagement between spring and element. The actuator may be slidably or pivotally supported in the swtich case and 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 illuminating the rocker in the miniature switch made possible by this simplified switch construction of fewer component parts. Still further embodiments provide for a toggle style actuator having a movable contact capable of retention in a "center-off" position wherein the movable contact is releasably retained on shelf-like lands defined for this purpose in the switch base, and wherein this contact can be moved by the depending actuator portion through joint action by the actuator and the spring provided on said actuator.
