When the first cold light portion 72 and the two second cold light portions 74 are electrically connected to the driving unit 90, the first cold light portion 72 and the two second cold light portions 74 are loaded with the same voltage to emit light of the same brightness. The first cold light portion 72 and the second cold light portion 74 are fixed to the position of the light transmitting member 80 facing the second through hole 11. Thus, when the first cold light portion 72 and the second cold light portion 74 emit light, the emitted light is transmitted through the light. Item 80, which is visible to the user. Specifically, each of the luminescent portions includes an upper electrode sheet, a lower electrode sheet, and a fluorescent material sandwiched between the upper electrode sheet and the lower electrode sheet. When a voltage is applied between the upper electrode and the lower electrode, the fluorescent material emits light under excitation of an electric field. The fluorescent material is zinc sulfide.

In the present embodiment, the light transmissive member 80 includes a base portion 82, a protruding portion 84, and two fixing portions 86. The protruding portion 84 protrudes from the base portion 82 and is received in the second through hole 11 . The two fixing portions 86 respectively extend from opposite edges of the two base portions 82, and the two fixing portions 86 are fixed to the inner side of the outer casing 10. Referring to FIG. 5 , the two fixing portions 86 respectively form a plurality of fixing holes 85 . A plurality of fixing posts 12 are protruded from the inner side of the outer casing 10. The plurality of fixing posts 12 are disposed in the plurality of fixing holes 85 and are fixedly connected to the light transmitting member 80 by heat fusion. The light transmissive member 80 has elasticity, and a pressing member 88 that faces the switch 60 is convexly disposed on a side facing the switch 60.
