チが切換つてしまうおそれがあつた。 In conventional electronic watches, the switch mechanism with dual stability of ON and OFF has a groove etc. on the outer diameter of the winding stem, and an elastic positioning switch member made of another member is engaged with this groove, and the push and pull of the winding stem is The elasticity of the elastic positioning switch member was used to sense the click of the winding stem and position it, as well as turn the switch ON and OFF. However, in order to provide the above-mentioned grooves on the winding stem, the winding stem must be made thicker, which poses a major design restriction. Also, when positioning the switch ON/OFF using the groove in the winding stem, the winding stem needs to have two push/pull operating positions.
In this state, when force was applied to the winding stem during use, there was a risk that the switch would change.

作でスイツチレバー４は第１図Ａの状態となる。 Next, to explain the operation, when the winding stem 1 is rotated in the direction of arrow a from the state shown in FIG. Then, the cam 3a provided on the operating cam 3 engages with the operating cam contact terminals 4a, 4a' of the switch lever 4 through the window 1a of the main plate, and accordingly, the cam 3a provided on a part of the operating cam contact terminal The elastic portion 4c is bent, and in this contact state, the actuating cam 3
As the switch lever 5 is rotated, the operating cam contact terminal collides with the protruding part 4b, and the switch lever 4 moves over the peak of the switch lever positioning part 5b provided on the positioning lever 5 with the pin 9 as the center of rotation, and moves to another valley. When it rotates until it reaches another valley, the collision with the protrusion is released. At the same time, the contact spring 4f of the switch lever 4 contacts the switch pin 10, turning the switch ON.
The state shown in FIG. 1B is reached. Furthermore, in this state, if the force of the actuating cam 3 is still applied, the elastic part 4c is bent by the amount of the opening of the actuating cam contact terminal of the switch lever 4, and as a result, the actuating cam contact terminal is removed from the rotation locus of the actuating cam. , is maintained in the state shown in FIG. 1B, and the force of the operating cam can be released. When the winding stem is rotated in the opposite direction, the switch lever 4 will be in the state shown in FIG. 1A in exactly the same manner as described above.
