PURPOSE:To provide many switch inputs with a small number of switch terminal patterns by providing the plural switch terminal patterns on a circuit substrate and providing a projecting part or recessed part on an external rotating bezel. CONSTITUTION:The plural projecting parts 1a are provided on the lower surface of the external rotating bezel 1, which surface faces a case band 2. The plural switch input means consisting of mode selecting switch buttons 7, mode selecting switch plates 9 and the switch terminal patterns 12a are provided in correspondence to these parts. For example, the circuit substrate 12 is provided with the four switch terminal patterns 12a to 90 deg. interval thereon and the external rotating bezel 1 is provided with the five recessed parts or projecting parts at every 30 deg. and one in the position of 60 deg. from the fifth recessed part or projecting part on the same circumference as the switch terminal patterns 12a in order to make switch input by rotation. The 12 switch inputs are obtd. if the bezel 1 is rotated once in this case. |
