    • A base button 4 wuth a button depressing surface and a shaft portion, and a shaft supporting portion for slidably supporting the shaft portion of the button base 4 are provided. A switch base installable on a print wiring board, a contact rubber providing a conductive portion at a position facing the print wiring board , and a light emitting portion provided on the print wiring board are also included. The shaft portion is lowered by depressing the button depressing surface of the button base 4 and the conductive portion of the contact rubber is lowered until the conductive portion contacts an electrical contact on the print wiring board. Thus, an electrical contact function is exerted and the light emitting portion emits light, when the conducts portion comes into contact with the electrical contact.
    • 基座按钮4设置按钮按压面和轴部,并且设置用于可滑动地支撑钮扣座4的轴部的轴支撑部。 可以安装在印刷线路板上的开关底座,在面向印刷线路板的位置处提供导电部分的接触橡胶以及设置在印刷线路板上的发光部分。 通过按下按钮基座4的按钮按压表面来降低轴部分,并且接触橡胶的导电部分降低直到导电部分接触印刷线路板上的电接触。 因此,当导电部分与电触点接触时,发挥电接触功能并且发光部分发光。
