Claims

[Scope of utility model registration request]

It is formed at the center of a switch case with a plurality of fixed contact pieces fixed to the bottom wall side and a conductive spring plate arranged on the switch case facing the fixed contact pieces, and can be reversed and deformed by pushing operation. a dome-shaped reversing spring portion; and a pair of concave beam portions formed on the spring plate on both sides of the reversing spring portion and having a curvature opposite to that of the dome-shaped reversing spring portion. and a pair of convex portions formed on the switch case and abutting on the respective center portions of both the beam portions, and the deformation of the beam portions when subjected to a pushing operation causes 1.
A push-button switch characterized in that it is configured so that the operating feel of the second step is obtained by the reversal deformation of a dome-shaped inversion spring portion.
