Claims

[Scope of utility model registration request]

A dome-shaped leaf spring is placed in the hole of the housing, a cover with a protruding pressing part is placed over it, and a protrusion for restricting movement formed on the side surface of the housing is formed at the same time as the cover is bored on the side surface of the cover. In a key switch in which a cover is movably inserted and opened and closed by pressing down a leaf spring in the housing with the pressing part of the cover, the key switch opens and closes by repeatedly operating the leaf spring inside the housing. Keith, Itsuchi is characterized by a cover guide protruding along the direction of movement of the cover.
