    • A movable contact unit includes a light-guide sheet, a cover sheet, a movable contact, and a light-transmissive light-guide portion. The light-guide sheet includes a film-shaped substrate, and a convex and concave luminescent portion provided on the substrate. The cover sheet faces the substrate. A dome-shaped resilient movable contact made of a thin metal sheet is attached to the cover sheet at a position corresponding to the luminescent portion. The light-guide portion is provided on the cover sheet at a position other than an area where the movable contact is disposed or on the light-guide sheet at a position other than an area where the light-guide portion is disposed. If the light-guide portion is provided on the light-guide sheet, the movable contact may be attached to the light-guide sheet without using the cover sheet.
    • 可动接触单元包括导光片,覆盖片,可动接点和透光导光部。 导光片包括膜状基板和设置在基板上的凸凹发光部。 封面面向衬底。 在与发光部对应的位置处,在覆盖片上附着由薄金属片构成的圆顶状弹性活动触点。 导光部在除了设置有可动触点的区域以外的位置处设置在覆盖片上,或者在除了配置有导光部的区域以外的位置处设置在导光片上。 如果导光部设置在导光片上,则可以在不使用盖片的状态下将可动触头安装在导光片上。
