ABSTRACT:
It is intended to provide a push-button switch capable of providing a comfortable and natural click touch. To achieve the purpose, the button turns downward about the point which joins the buckling wall to the base on the back face side. Accordingly, the pulling force on the buckling wall does not occur when the button is pressed. Consequently, a user needs less pressing force, and can feel a clear and quite natural click touch.
