ABSTRACT:
A backlit LCD is mounted in a controller having push buttons operating switch elements in a molded elastomeric switch pad for bridging pairs of switch terminals on a circuit board. The switch pad is white to reflect light and a portion of the switch pad behind the LCD is curved to serve as a reflector. A lamp between the display and the reflector illuminates the rear of the display directly and via reflection from the curved surface of the switch pad. This obviates the necessity of a separate reflector part in the controller assembly.
