Claims

[Scope of utility model registration request]

a switch case, a stem whose vertical movement is guided by the switch case, a spring which applies an upward spring force to the stem, and a contact circuit which is disposed within the switch case and opens and closes by the vertical movement of the stem. a switch element; an upright part that comes into contact with the inner wall of the switch case; a leaf spring part that extends from the upper end of the upright part to a vertical movement area of the stem; and a click protrusion provided at the tip of the leaf spring part. A push button switch comprising: a click spring having protrusions bent at a substantially right angle from both ends of the upright portion and tapered on the lower side.
