Claims

[Scope of utility model registration request]

A key top is supported in the case so as to be movable up and down, and a membrane switch is disposed below the key top, and a spring member is interposed between the membrane switch and the key top, so that the spring pressure of the spring member as the key top lowers causes the membrane to move up and down. In a push button switch configured to allow the contact portions of the switch to come into contact with each other, a mounting surface portion on which the membrane switch is placed is formed on the upper surface of the case that supports the key top so that it can be raised and lowered, and the contact portion of the membrane switch is directly placed on the mounting surface portion. A push-button switch characterized by the fact that
