Abstract
A combination input unit comprises a printed circuit board, a press key, a retaining bracket, a light transmissive rotary dial, and a housing. The printed circuit board accommodates an encoder circuit, a plurality of contacts, and a plurality of light sources. The press key is disposed above the contacts, and comprises a flange thereof. The retaining bracket is fitted over the press key and connects the press key to the printed circuit board. The light transmissive rotary dial is rotatably fitted over the press key. The rotary dial is positioned above the encoder circuit, comprises at least one elastic piece for resiliently pressing the encoder circuit, and a reflective surface. Light emitted by the light sources are reflected by the reflective surface, thus to illuminate the whole rotary dial. The housing receives the press key, the rotary dial, and the printed circuit board.
