PURPOSE:To eliminate the protrusion of a push button switch and to enhance switching operation. CONSTITUTION:A protruding part 3 is provided to the side surface of a wristwatch case 1 and a push button switch 5 is arranged to the lower part of the protruding part 3 and an operation member 2 is pivotally supported on the protruding part 3. The operation member 2 is made revolvable downwardly around the pin 10 of the protruding part 3. The press part 23 of the operation member 2 is brought into contact with the head 5a of the push button 5. When the operation part 22 of the operation member 2 is subjected to pressing operation, the press part 23 presses the push button switch 5 horizontally to perform switching. Since the push button switch 5 does not protrude, a design is enhanced and, because of the switching downwardly pressing the operation member 2, operability is enhanced. |
