PROBLEM TO BE SOLVED: To provide a switch having a uniformly illuminated pattern.SOLUTION: A first detection or a second detection is performed by a touch sensor 32 in a switch 30. When any one of LEDs 34a and 34b is illuminated, light radiated from the LED 34a or 34b is dispersed by a periphery side surface of a chamfered guiding board 33 and contained by the guiding board 33 and is diffused to the entire guiding board 33. The diffused light is incident on a periphery side surface 33a of the guiding board 33 within the guiding board 33 and is repeatedly reflected and diffused, and therefore the light is uniformly incident on a cut part 33d provided in the guiding board 33 and is irregularly reflected by the cut part 33d. When the LEDs 34a and 34b are turned on, a portion where the cut part 33d is provided can be lighted brighter than an area surrounding the portion, and a pattern ("A" in a Fig.3 ) corresponding to a switch 30 can be uniformly illuminated.SELECTED DRAWING: Figure 3 |
