摘要

All housing parts (2-6) are made of plastic light guide material. Light impinging on outside (9) of housing is guided into housing parts and exits at edges thus gap (8) between housing parts is illuminated so buttons (4,5) and intermediate part (6) are clearly differentiated. Edges are beveled to increase visibility of gap. Base has colored or reflective coating to provide color effect at gap.
