Abstract
An improved push button assembly having solid state light sources may be utilized to replace push button assemblies having incandescent light sources in previously installed switch assemblies or may be used in original equipment. The push button assembly includes a base which at least partially encloses a printed circuit. A plurality of solid state light sources are connected with the printed circuit. A display is illuminated by light from the solid state light sources. One or more electrical circuit components, which emit heat, are connected with the printed circuit. A metal heat sink is disposed adjacent to the electrical circuit components. The metal heat sink engages a metal housing which encloses a display which is illuminated by light from the solid state light sources.
