Claims

[Scope of utility model registration request]

An insulating base made of an elastic insulating member is superimposed on a lower electrode made of a conductor and provided with a plurality of small holes, and a convex part formed integrally with the insulating base protrudes from the small hole. a dot spacer, a flexible insulating sheet on which an upper electrode is formed on one side is placed on the insulating base via the dot spacer, and both the upper and lower electrodes are connected via the dot spacer. Menzurren switch characterized by facing each other.
