PROBLEM TO BE SOLVED: To provide a switch device capable of increasing impact resistance by relaxing an impact from the outside.SOLUTION: The switch device includes: a cylindrical member 7 mounted on a through-hole 12 of a wrist watch case 1; an operation member 8 having an operation shaft part 17 to be inserted into the cylindrical member 7 and an operation head 18 of an outer end part; a buffer member 10 mounted on the operation head 18 such that it is covered; and an exterior member 11 fixed to the operation head 18 such that the buffer member 10 is covered, and that the plurality of places of the buffer member 10 are protruded to the outside. Therefore, when the exterior member 11 receives an impact from the outside, the impact can be relaxed by the buffer member 10 protruded from the exterior member 11 to the outside. Thus, it is possible to prevent the damage of the operation member 8 or the cylindrical member 7 due to an impact from the outside, and to increase impact resistance. |
