At this position, after being inserted into the first operating rod 10, it is engaged and fixed with the elastic engagement piece 10a. Furthermore, an operating knob 11 for rotating the operating lever shaft 6 is fixed to the other end of the operating lever shaft 6 with a screw 24 . An operating lever 7 is located below the first operating rod 10.
An operation protrusion 10b is formed that penetrates through the through hole 7e and projects to the lower surface, and engages with an engagement protrusion 12a of a cam disc 12 installed at the lower part of the operation lever 7. A moderation mechanism consisting of a spring 13 and a steel ball 13a is inserted into the first operating rod 10, and a moderation ridge 7f is formed on the operating lever 7, and the moderation mechanism is configured to adjust the rotation angle according to a predetermined rotation angle. It has a moderation device that is engaged and restrained. At a position in front of the through hole 7e in the operating lever 7, that is, in a position in front of the first operating lever 10, a second operating lever 25 protruding from the lower surface is fixed by integral formation or screwing. .

The movable contact pieces 19, 20, 21 are switched by the push rods 16, 17, 18, which are moved up and down by the movement of the cam disc 12 having the cam surface 12b, and are operated by the swinging operation of the operating lever 7 in the up and down direction. This constitutes a second switch that is activated, and a third switch that is activated by rotating the operating knob 11.

A first switch 23 is fitted into the movable member 3 and is operated by swinging the control lever 7 in the left-right direction, and has a direction indicating switch function.

Next, the operation of the above configuration will be explained.

In Fig. 2, when the operating lever 7 is operated to the L position, the left direction indicator light is turned ON so as to blink due to the action of the first switch 23, and in the R position, the right direction indicator light is blinked. It is turned ON. Further, at the neutral position N, it is in the OFF state.

Next, in the configuration in which the operating lever 7 is operated in the vertical direction, there are three positions, D, M, and P positions, as shown in FIG. In this position, the upward direction of the headlight is lit. In addition, in the P position, the upward direction of the headlight can be turned on regardless of day or night, that is, the control lever 7 is connected to the moderation ridge 3b forming the moderation device of the movable member 3 and the control lever 7 so that the control lever 7 is automatically returned from the P position to the D position. By being configured with the inserted elastic contact member 8, it is easy to repeatedly operate from the D position to the P position, and the headlight can alternately flash downward and upward at night, and during the day, the headlight can be turned on and off alternately. It is possible to blink the upward direction.

That is, it functions as a main/damer switch and a passing switch.

Next, in the configuration in which the operation knob 11 is rotated, there are three positions, OFF, , and OFF, as shown in FIG. In the OFF position shown in the figure, the switch does not operate in the D or M positions except for the P position, which is the vertical operation position of the main dimer changeover switch.
In other words, neither the downward nor upward directions of the headlights are turned on, and in this position, the taillights, etc. are turned on, and the headlights do not switch even in this position. Further, in the position, the headlight is turned on.

The operation of the light switch control mechanism that performs such a switch operation is as follows.

When the operating knob 11 is rotated, the first operating rod 10 is also rotated, and the operating protrusion 10b engages the engaging protrusion 12a.
is pressed to move the cam disk 12 in the left-right direction.
Thus, the push rods 16, 17, 18 move forward and backward in correspondence with the cam surface 12b of the cam disk 12 to open and close the movable contact pieces 19, 20, 21 as switches.

Further, when the operating lever 7 is operated to swing in the vertical direction, the second operating rod 25 swings back and forth, and the guide plate 14 is moved back and forth by pressing the wall surface of the second engagement hole 14b. Then, the guide disk 14 moves the cam disk 12 in the front-back direction due to the engagement relationship between the engagement protrusion 12a and the first engagement hole 14a.
Thus, the push rods 16, 17, 18 also move forward and backward in correspondence with the cam surface 12b of the cam disk 12 to open and close the movable contact pieces 19, 20, 21 as switches.
