ABSTRACT:
A push-push latching switch assembly having a switching member with a pushbutton which is received for sliding movement in a switch housing. The housing has spring tabs for snap locking insertion into a hole in a mounting panel. The switching member has lamps disposed in a receptacle portion beneath the button which has translucent lens portions for illumination by the lamps. The switching member has conductive strips formed by plating over two-shot integrally molded plastic strips, with the conductive strips interconnecting the lamps and wiper contacts attached to the switching member. A conductive wiper member with plural wiper fingers is also attached to the switching member. A base member formed of two-shot molded plastic has conductive switching contact strips formed by plating the second shot molded plastic and which are inserted in the housing, with the base releasably attached. User pressure on the button causes the switching member to move relative to the housing sliding the wipers on the strips for switching and continuously providing power to the lamps. The conductive plated strips extend externally to form connector pins. A cardiod cam and latch provide the push to latch, push to unlatch function.
