Characters, symbols, etc. punched into the light shielding material layer 17 are displayed on the key top 16a by illumination.
このように構成したため、キートツプ１６ａが
自身の内側からの光照射により照らし出され、夜
間などにおけるスイツチ操作を容易に行なうこと
ができる。 With this configuration, the key top 16a is illuminated by light irradiating from inside itself, making it easy to operate the switch at night.
また、透光弾性領域６は乳白色のシリコンゴム
に銀粉を混入して注型しているため、入射光が乱
反射して明るい照光表示を行なうことができる。 Further, since the light-transmitting elastic region 6 is made of milky white silicone rubber mixed with silver powder and cast, the incident light is diffusely reflected and a bright illuminated display can be performed.
さらに、透光弾性領域６は、透明板３に形成し
