摘要： A switch device of the present invention includes a cylindrical member attached to a through hole of a wristwatch case, an operation member having an operation shaft section inserted into the cylindrical member and an operation head section provided at the outer end of the operation member, a cushioning member attached to the operation head section of the operation member to cover the operation head section, and an exterior member fixed to the operation head section to cover the cushioning member and from which a plurality of portions of the cushioning member project outwardly. Therefore, when the exterior member receives an external impact, the impact can be mitigated by the cushioning member projecting outwardly from the exterior member. As a result, the operation member and the cylindrical member can be prevented from being damaged by the external impact, whereby the impact resistance can be increased.
