<P>PROBLEM TO BE SOLVED: To obtain a cheap switch connection structure not abnormally abrading or distorting the contact spring 3a of a support plate 3 even with repeated operation of an external operation member 4 of a push button and the like by installing a movement 1 of a basic shape in a timepiece case 5 with different shape from the basic shape of the movement 1. <P>SOLUTION: The structure has a support plate 3 capped on the timepiece movement 1 and provided with a contact spring 3a of which the contact point 3b at a tip end contacts the switch contact point 2a of a circuit board 2, and a switch click plate 6 covering at least a part of the support plate 3, whereat a switch spring 6a corresponding to the contact spring 3a is provided in the outer part. When the switch spring 6a bends by operating an external operation member 4 installed in a timepiece case 5, the contact point 3b of the contact spring 3a of the support plate 3 contacts the switch contact point 2a of the circuit board 2. The switch spring 6a of the switch click plate 6 plays a role of properly transmitting the pressure of the external operation member 4. <P>COPYRIGHT: (C)2004,JPO |
