摘要： A push button-type switch device includes a pair of fixed contacts, an operable member to be pushed, an actuating member elastically deformable upon the operable member being pushed, a movable contact which short-circuits the pair of fixed contacts due to elastic deformation of the actuating member, and a limiting part arranged to limit a direction in which the operable member moves and making the operable member move in a fixed orientation. The limiting part includes a pair of link members that engage with each other, one ends of the link members rotatably supported by the base portion, and the other ends thereof slidably supported by the operable member. This produces a good click irrespective of a position where the operable member is operated.

摘要： The keyboard includes a rubber sheet fixed on key tops of a set of key-switch devices. The rubber sheet elastically urges the key tops upward so that they are borne away from the base of the key-switch devices. The rubber sheet is arranged so as to cover the key-switch devices from outside. According to the invention, the cost of a keyboard covered with a dustproof and watertight rubber sheet can be reduced.
