Abstract
A pushbutton assembly for panel arrays of pushbuttons has a pushbutton assembly comprising an LED extended through a guide bushing and connected to a first printed circuit board. The guide bushing is mounted to the first printed circuit board. A movable cover over the LED has pins extending through guide bores in the guide bushing with an actuator plate mounted to the pins on the opposite side of the first printed circuit board from the cover. A second printed circuit board spaced apart from the first has spring-loaded pushbutton switches mounted thereto, with the spacing such that pressing on the cover activates the pushbutton switch by means of the activator plate. The assembly of two boards may have any convenient array of switches assembled thereon, with the switch signals routed on one board and the driving signals for the LEDs routed on the other. The assembly of printed circuit boards is mounted with the covers protruding through a panel to present an array of lightable switch covers to an operator.
