Abstract
An illuminated pushbutton for a pushbutton switch having a light transmitting pushbutton and an indicia cover that is attached to a front end of the light transmitting pushbutton. The indicia cover has non-light transmitting regions and light transmitting regions on its front surface, wherein the light transmitting regions provide visible, light-transmitted indicia on the light transmitting pushbutton. The indicia cover has an adhesive on its rear surface to attach the indicia cover to the front end of the light transmitting pushbutton. An LED in the pushbutton switch is constructed to transmit light to the indicia cover. The light passes through the light transmitting regions (symbols and letters) but not through the non-light transmitting regions. As the light passes through the light transmitting symbols and letters, the symbols and letters are lighted and visible in the dark.
