| 摘要 | PURPOSE:To reduce the burden in fabrication and achieve the improvement in waterproofness by the constitution wherein a switch unit assembled and disposed with a plurality of electric switches is inserted into the watch case. CONSTITUTION:A switch unit 20 mounted with a cover 22 on its base body 21 is mounted with a waterproof packing 24 in the circumferential groove 21C of its stem part 21a and is inserted into the through-hole 11 of a watch case 10. Here, the differently shaped part of the switch unit 20 is disposed to the step part 12 of the watch case 10 and a stop ring 25 is mounted to the base body 21. Terminals 27 of the base body 21 make contact to the contact part 31 of the module 30, thereby taking electrical conduction. A plurality of conductive rubbers 22b are integrally provided to the bottom side of the cover 22 and so arranged that when the cover 22 is pressed they make contact to the terminals 28 at the top of the base body 21 and this constitutes the electric switches. | ||||||
