ABSTRACT:
A round illuminated button pin is back-lit by internal miniature incandescent lamps or LEDs (light emitting diodes). The image is not punctured by the lights -- rather, it is printed on a flat disk of transparent or translucent polystyrene (or other suitable plastic). A removable cap of rigid transparent plastic, such as molded acrylic, covers and holds the image. When the cap is removed, the planar circular image disk is loose, except for a pair of positioning notches in its diameter which capture a pair of lugs to keep the image from rotating within the cap. The image disk may quickly be removed simply by turning the button upside down, whereupon it will freely fall out. This allows one button to be reused with any number of interchangeable alternate images.
