Claims

[Scope of utility model registration request]

In the push button switch, the casing has a switching element storage chamber in which a fixed contact is arranged at the bottom thereof, and a dome spring and a key top are inserted into the switching element storage chamber from an upper opening thereof. The element storage chamber is provided with a fulcrum support groove in a part of the periphery of its opening, and has an eave around the whole or part of the periphery of the opening, and the size of the flange of the key top is made smaller than the opening narrowed by the eave. Make the key top slightly larger, form a fulcrum side on a part of it, and press and fit this key top through the opening using the elasticity of the eaves and flange so that the fulcrum side fits into the fulcrum support groove. A push button switch characterized in that it is mounted inside a switching element storage chamber.
