摘要： A coil spring constituting a pushbutton switch includes an intermediate diameter coil spring part serving as a tension spring coil spring part serving to depress a movable contact. This reduces the number of parts being needed. In addition, a housing guides a pushbutton support arm fixedly inserted into a groove formed between the casing and a guide part and the tip end of the support arm is adapted to strike the bottom of the housing in depression of the pushbutton and is thereby stopped, while the tip end is stopped by a stopper when the support arm is returned. Moreover, a projection part of a pushbutton body is pushed into the coil spring whereby the intermediate coil spring part is elongated while the small diameter coil part is contracted for closing the contacts, the contacts thereupon being released by the return of the pushbutton.
摘要翻译：构成按钮开关的螺旋弹簧包括用作按压可动触头的拉伸弹簧螺旋弹簧部分的中间直径螺旋弹簧部。这减少了所需的零件数量。此外，壳体引导固定地插入形成在壳体和引导部分之间的凹槽中的按钮支撑臂，并且支撑臂的末端适于在按钮的按压中击打壳体的底部并由此停止，同时当支撑臂返回时，末端被止动器挡住。此外，按钮体的突出部分被推入螺旋弹簧中，由此中间螺旋弹簧部分是细长的，而小直径线圈部分收缩以闭合触点，然后通过按钮的返回释放触点。
