Claims

[Scope of utility model registration request]

At the fixed contact of the wiring pattern provided on the board,
A switch mechanism in which a contact member made of an elastic material is fitted into a contact member support portion of a movable member that is movable while being guided by a guide portion of a frame provided on the substrate, and the contact member is press-contactable. In a switch mechanism in which the member is made of a rubber material and a contact portion is provided on the lower surface, the contact member is formed in an elongated plate shape, and at least the contact portion is made of a conductive rubber material, In addition, a bulge is provided on both ends of the movable member to protrude substantially perpendicularly thereto, and a bulge is provided on the lower side of the movable member that is guided and movable by the guide portion of the frame in a direction substantially perpendicular to the sliding direction of the movable member. The contact member support part that is provided in a protruding manner and is integrally molded with the movable member is provided with an upper surface tapered part at both ends thereof, and the bulge part provided on the contact member is inserted into the tip of the tapered part. In the switch mechanism, the bulging portion is inserted into the insertion hole, and the bulging portion is elastically crimped to the tapered portion provided on the contact member support portion. contact device.
