PURPOSE:To decrease the number of component parts concerning the switch by using one through-hole as a pair of switch contacts, and thus to realize miniaturization of the movement. CONSTITUTION:A pair of switch contacts 10a and 11a perform an electric contact in correspondence to switch bar 2 featuring the reciprocal motion interlocking the operation of setting stem 1. And contact 10a and 11a also function as a pair of electrode pattern 10a and 11a which are formed by dividing electrode pattern 13 of through-hole 8 formed to circuit substrate 4. |
