The switch device 11 is used, for example, in a lighting system in which a human body is detected by a human sensor and the lighting device is automatically turned on. In this case, as shown in FIG. 12, the switch device 11 is used for switching the operation mode of the lighting system, and "automatic" is an automatic mode in which the human body is detected by the human body switch and the lighting device is automatically turned on. "" Is switched to the on mode in which the lighting device is always turned on, and "off" is switched to the off mode in which the lighting device is always turned off. Then, in the switch device 11, the wiring for configuring the automatic mode is connected to the first load terminal 52, and the wiring for configuring the ON mode is connected to the second load terminal 53, and the automatic mode and the ON mode are connected. Common wiring is connected to the common terminal 54.

Then, FIG. 9 shows a switching state in which the knob 22 is in the “off” position.

At the cut position of the knob 22, the shaft body 55 is at the cut position where the center line a in the opening direction of the through opening 71 faces the middle between the first load terminal 52 and the second load terminal 53. The shaft body 55 at the cut position is not in contact with the movable piece 63.

Therefore, the movable piece 63 is placed at a cut position where the contact portion 69 at the tip of the movable piece portion 68 is an intermediate position between the contact portion 60 of the first load terminal 52 and the contact portion 60 of the second load terminal 53. positioned. That is, the movable piece 63 is located at a cutting position where neither the contact portion 60 of the first load terminal 52 nor the contact portion 60 of the second load terminal 53 is in contact with each other.

The leaf spring 56 abuts on the peripheral surface of the rotation position holding portion 76 of the first shaft member 72, that is, abuts on the hexagonal holding surface 81, and holds the shaft body 55 at the cutting position with a predetermined holding force. There is.

Hold with the holding power of. The holding surface 81 with which the leaf spring 56 abuts at the second connection position is the holding surface 81 located next to the holding surface 81 with which the leaf spring 56 abuts at the cutting position. Then, just before the shaft body 55 rotates to the second connection position, the shaft body 55 is forcibly rotated by the spring force of the leaf spring 56, and the shaft body 55 rotates to the second connection position. When the leaf spring 56 comes into contact with the holding surface 81, a click feeling of the switching operation by the knob 22 is obtained and a switching sound is generated, so that it is easy to grasp the switching of the knob 22 to the “on” position.

In the switching state in which the shaft body 55 is rotated to the second connection position, the contact portion 69 of the movable piece 63 is pressed against the contact portion 60 of the second load terminal 53, and a good electrical connection state is maintained.

Then, when the knob 22 is rotated from the “on” position to the “off” position, the shaft body 55 rotates clockwise from the second connection position toward the cut position in FIG. 11, and the shaft body 55 Both the movable piece 63 and the movable piece 63 return to the cutting position shown in FIG.
