PROBLEM TO BE SOLVED: To provide a seal type push button for a wrist watch including a push button head which is movable between a static position and an active position, a first fixed conductive element, and a second movable conductive element.SOLUTION: A seal type push button includes an elastically deformable capsule 60 which seals and covers a first fixed conductor 5, and a top face 621 of the capsule 60 comes into physical contact with a bottom face 121 of a push button head 1. The capsule 60 can be located at a position which is not deformed when the push button head 1 is located at its static position Pr, and can be located at a deformed position when the push button head 1 is located at its active position. The first conductive element 5 and a second conductive element 6 form a capacitive switch device or a resistance switch device. The switch is in an open state when the push button head 1 is located at its static position Pr, and is in a closed state when the push button head 1 is located at its active position. |
