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.
Claims8
A push-button switch comprising:
- a base;
- a buckling wall extending from the base;
- a button connected to the buckling wall, and provided with a front face, a back face, a left side face, and a right side face;
- a board on which the base is placed;
- a cover body provided with a through-hole through which the button protrudes, while keeping a clearance with respect to the front face of the button;
- a rib formed as a protrusion on the bottom face of the button near the back face, the rib being separated from the board when the button is unpressed, and brought into contact with the board and preventing a buckling deformation of the buckling wall on the back face side when the button is pressed;
- a movable contact formed as a protrusion on the bottom face of the button, nearer the front face side than the rib, to face fixed contacts provided on the board, the movable contact being apart from the fixed contacts when the button is unpressed, and allowing a buckling deformation of the buckling wall on the front face side when the button is pressed;
- and
- a supporting point which is a point joining the base and the buckling wall of the button on the back face side, wherein the button turns around the point when the button is pressed.
