Abstract

A main plate at which a watch component is disposed, a circuit board including a regulating pattern, a regulating switch disposed contactably with the circuit board, and a holding member disposed on a side opposite to the circuit board with respect to the regulating switch are included, the regulating switch includes a guide pin fixed to the main plate, a lever body including an opening portion into which the guide pin is inserted and a contact portion that contacts the regulating pattern, and a coil spring including an opening portion into which the guide pin is inserted and presses the lever body toward the circuit board, and the holding member holds the coil spring sandwiched between the holding member and the lever body.

First claim

What is claimed is:

1 . A watch, comprising:
a main plate at which a watch component is disposed; a circuit board having a first surface and a second surface outwardly opposite to each other, the first surface of the circuit board including a regulating pattern; a rotary switch disposed contactably with the circuit board; and a holding member disposed on a side opposite to the circuit board with respect to the rotary switch, wherein the rotary switch includes:
a guide pin fixed to the main plate, the guide pin being elongated along a first direction;
a lever body including a first opening portion into which the guide pin is inserted, a first lever part having a contact portion that contacts the regulating pattern, and a second lever part having a knob, the first and second lever parts of the lever body being elongated from the first opening portion toward an outside in different directions, respectively; and
a coil spring disposed between the holding member and the first and second lever parts of the lever body along the first direction, the coil spring including a second opening portion into which the guide pin is inserted, the coil spring pressing the lever body toward the circuit board,
a distal end of the second lever part of the lever body is located closer to the holding member than a proximal end of the second lever part of the lever body along the first direction, and a proximal end of the first lever part of the lever body is located closer to the holding member than the contact portion of the first lever part of the lever body.

2 . The watch according to claim 1 , wherein
the guide pin and the holding member abut against each other when impact is applied.

3 . The watch according to claim 1 , wherein
the rotary switch includes a cylindrical lever shaft into which the guide pin is inserted and to which the lever body is fixed.

4 . The watch according to claim 3 , wherein
the cylindrical lever shaft includes a flange that contacts the lever body.
