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 contacts the inner wall of the switch case; a leaf spring part extending from the upper end of the upright part to the upper and lower regions of the stem; a click protrusion provided at the tip of the leaf spring part; It is characterized by comprising a click spring having a protrusion piece bent at a substantially right angle from both ends of the upright part and tapered on the lower side, and a slit part formed by cutting out the vicinity of both ends of the upright part from above. A push button switch.
