ABSTRACT:
A push button switch has a housing formed by a base in which a fixed contact is disposed on a bottom face of the base and a cover assembled to the base, an operating member slidably inserted in the housing parallel to the bottom face of the base, a guiding part formed on the cover, extending obliquely inwards from a ceiling face of the cover, wherein a tip of an operating piece of the operating member is operable to slide along the guiding part, and a movable contact disposed in the housing and operable to be pressed against the fixed contact, thereby opening a circuit. The guiding part and a reinforcing part extending from the ceiling face of the cover at least on one side of the guiding part are formed at an edge of a through hole formed in the ceiling face of the cover. The movable contact has a thin dome shape.
