PURPOSE:To prevent malfunction and improve manufacturing fabrication characteristic, assembling characteristic and volume productivity by so constituting the touch switch for correction that it may be used by changing only a part of the parts of other touch switches. CONSTITUTION:Two touch switches 3a, 3b are provided on the lower side of the display part 2 of a watch case 1. The touch switch 3b on the left side is a touch switch for correction and is so formed as to cover the outside circumferential part of an electrode body 7 by extending the exposed part 6a of an insulator 6. The area of its touch area 7a is made smaller than that of the display changeover switch 3a on the right side. When the finger is placed on the display changeover touch switch 3a and simultaneously touches the watch case 1 and electrode body 7, the body resistance 15 by the finger of the hand is formed and the output is produced from an output terminal 16a, but since the extension part 6a of the insulator 6 is formed in the touch part of the touch switch 3b for correction, malfunction may be prevented. |
