PROBLEM TO BE SOLVED: To perform switch operation effectively by making a base member diffuse the illumination light from back with good balance thereby making the letters in the printed layer at the roof of an operation member easy to see. SOLUTION: A base member 25 is attached through a hinge 26 to a retaining frame 24. An actuator 27 to abut on a switch is made at the rear of the base member 25, and a fusing pin 29 for fusing an operation member 28 together by heat is made on the front side. These retaining frame 24 and base member 25, a hinge 26, an actuator 27, and a fusing pin 29 are made by integral molding of resin. The operation member 28 is made of transparent or colored transparent resin, and a printed layer 31 to show letters such as 'TV', 'NV', etc., to show the function of a switch is applied to the roof. When an LED 49 is lit, the light emitted from the LED 49 is diffused enough when passing the base member 25 made of semitransmitting diffusion material. Accordingly, the background of letters, etc., drawn at the operation member 28 is illuminated equally, a button easy to see is obtained. |
