Next, to describe the operation, first, in the above structure, the operating lever 1 is attached to the shaft protrusions 20, 23 of the bracket 12.
It is possible to operate the bracket 12 and the lever holder 7 upward and downward (up and down in FIGS. 4 and 5), that is, in the first rotation direction, with the bracket 12 and the lever holder 7 at the center. With the lever holder 7 at the center, it is possible to operate forward and backward (up and down in FIG. 3), that is, in the second rotation direction, and in addition, the shaft pin 1
It is designed such that it can be moved independently in both the pushing and pulling directions in the axial direction by the extra length of the elongated hole 3 relative to the length of the elongated hole 3.
However, normally, the operating lever 1 has a protrusion 26 which receives the elastic force of the compression spring 27 in the first rotation direction.
is the central portion 41a which is the so-called valley bottom portion of the recessed portion 41.
By falling down and being pressure-welded, it is held at the neutral position _N1 , which is the original position that does not deviate upward or downward in Figures 4 and 5, and in the second rotation direction. The protrusions 43, 43 that have received the elastic force of the compression springs 44, 44 are the protrusions 10, 10 of the lever holder 7.
Since the inner surfaces 10a and 10a of the dogleg shape are depressed and pressed into contact with the center portion, which is also the valley bottom portion, there is no deviation upward or downward in FIG. 3 in the first rotational direction. It is held at the neutral position _N2 , and furthermore, in the axial direction, it is held at the neutral position N3 where it does not deviate to either the pushed-in position or the pulled-out position due to the elastic force applied to both ends of the notch 4 from the torsion spring ₂₄ . has been done. Therefore, such an operating lever 1 operates against the elastic force of the compression spring 27 in the first rotation direction, and against the elastic force of the compression springs 44, 44 in the second rotation direction. , and are operated in the axial direction against the elastic force of the torsion spring 24. Therefore, the operating lever 1 is now rotated in the first rotation against the elastic force of the compression spring 27. The lower part of the direction, i.e., Figures 4 and 5.
When the switch is operated downward in the figure, the first rod 49 attached to the bracket 12, which rotates clockwise in the figure, moves inside the outer casing 51 of the first switch X in FIGS. 4 and 6. The contact holder 53 is moved in the same direction by moving the contact holder 53 to the right and to the left in FIG. In other words, the small right turn signal lamp is connected to the right/left turn signal electric line via the power switch and flasher, and the small lamp is lit intermittently. Also, at this time, the bracket 12, which has been rotated clockwise in FIG. The pawl 29 receives the biasing force of the tension spring 35 via the tension spring 32, and the above-mentioned one side 29a is fitted into the recess 36 and engaged, so that the rotation of the bracket 12 is moderated and stopped, and the operating lever is 1 at the right turn signal position TR shown in the lower part of Fig. 4. The state of the pawl 29 area at this time is shown in FIG. 13. In this state, the steering wheel is first rotated in the right direction, so the cancel pin 40 moves clockwise as indicated by the arrow in the figure. However, in this direction, the rod 31 kicked by the cancel pin 40 only rotates the claw 29 using the one side 29a engaged with the recess 36 as a fulcrum to separate the other side 29b from the bracket 12. Therefore, the one side 29a continues to engage with the recess 36, and the operating lever 1 continues to be held at the right turn signal position TR. However, when the steering wheel is returned after turning right, the cancel pin 40 kicks the rod 31 to the opposite side, and the pawl 29 is moved to one side using the other side 29b that collides with the bracket 12 or the other blocking wall 39 as a fulcrum. Since the side 29a is rotated to separate from the recess 36, the restraint of the bracket 12 is released. Thus, the protrusion 26, which has been subjected to the elastic force of the compression spring 27 mentioned above, has moved beyond the area of the central part 41a of the recess 41 to a higher place as indicated by the upper two-dot chain line in FIG. However, as described above, when the restraint of the bracket 12 is released, the elastic force stored in the compression spring 27 is released, and the bracket 12 slides along the slanted surface of the recess 41 to the center portion 41a, thereby being adjacent to the center portion 41a. By extending the bracket 12, the operating lever 1 is returned to the neutral position _N1 . Therefore, here, the main point holder 53 in the outer casing 51 of the first switch At the very least, turn off the power to the small right turn signal lamp and return the lamp to its off state. On the other hand, when the operating lever 1 is operated upward, that is, upward in FIG. 4, everything works in the completely opposite direction to that described above. Since the contact plate 56 is moved to the right in FIG. 8 and the contact plate 93 is selected from the contact plate 94, the small lamp for the left turn signal is lit intermittently, and
The other side 29b of the pawl 29 is engaged with the recess 37, and the operating lever 1 is moved to the left turn signal position shown in the upper part of FIG.
TL, and further, the cancel pin 40 is moved only when the steering wheel is returned from the turning operation in the left-turning direction, so that the other side 29b of the pawl 29 is released from the recess 37, and the bracket 12 is held at the TL position.
When the restraint of the bracket 12 is released in this way, the operating lever 1 is moved back to the neutral position N ₁ by the protrusion 26 that slides down the sloped surface of the recess 41 in the opposite direction to that described above. and turn off the small left turn signal lamp.

Next, when the operating lever 1 is operated in the second direction of rotation against the elastic force of the compression springs 44, 44 toward the front of the driver (upward in FIG. 3),
A second rod 46 attached to the lever holder 7 that rotates with this is connected to the outer casing 10 of the second switch Y.
0 and inside the inner casing 101 to the right in FIG. 9 and to the left in FIG. 10 to move the transfer element 105 in the same direction. Then, the transfer element 105 engages with the upright surface of the engagement protrusion 117 of the contact holder 116, which is the mover, by the tip of the engagement piece 112 on one side of the leaf spring 109, and pushes this, further pushing the contact holder 116 into the second position. 9
Leaf spring 1 that moves to the right in the figure and to the left in Figure 10
The bulge 123 of 22 is connected to the trough 125 of the moderate mountain 124.
Since the contact plates 130 and 132 are also moved one step downward in FIG. 12 to move the contact part 134 to the next valley part 139,
Then, while the contact portions 136 and 137 are connected to the contact plate 140, the contact portion 135 is connected to the contact plate 13.
9 to the contact plate 138, in short, the small lamp of the auxiliary lamp is connected to the battery electric circuit, and the small lamp is turned on. When the operating lever 1 is operated as described above, the protrusions 43, 43 are compressed by the compression springs 44, 4.
The compression springs 44 are compressed to allow them to accumulate even more elastic force and come into sliding contact with the doglegged inner surfaces 10a, 10a of the protrusions 10, 10 of the lever holder 7, and when the operation is released, the compression springs 44 , 44 slides down the dogleg-shaped inner surfaces 10a, 10a of the protrusions 10, 10 toward their respective centers, and in this way, the operation lever 1 after the operation is released is automatically activated. Moreover, it is immediately returned to the neutral position _N2 . At this time, in conjunction with the return of the operating lever 1 as described above, the second rod 46 also returns the feeder 105, but the contact holder 116 holds the bulge 123 of the leaf spring 122 at the detent. 124 and is held in the position after the movement, the shifter 105 is held in the position after the movement by the leaf spring 109 while leaving the contact holder 116 in the position after the movement.
The aforementioned engaging protrusion 117 is attached to the engaging piece 112 on one side of the
Then, it passes over the slanted surface of the next engaging protrusion 118 and returns independently. In other words, since the transfer element 105 can be returned in this manner, the return of the operating lever 1 is also allowed and made possible (see FIG. 14). Now, when the operation lever 1 is operated forward again after returning, the same thing as described above is done, except that in this case, the transfer element 105 is moved to the engagement piece 1 on one side of the leaf spring 109.
The above-mentioned engaging protrusion 118 is crossed by the tip of 12.
Push the upright surface of the contact holder 116 further to the right in FIG.
132 is also moved one step further downward in FIG. 12, and while keeping the contact portion 134 in contact with the contact plate 139, the contact portion 135 with the contact plate 138, and the contact portion 136 with the contact plate 140, the contact portion 137 is moved. Contact plate 14
0 to the contact plate 141, in short, the small lamps of the auxiliary lamps and the low beam headlamp are connected to the battery electric circuit, and these lamps are turned on. Of course, at this time as well, after the operation is released, the operating lever 1 is automatically returned to the neutral position _N2 in the same manner as described above, and the transfer element 105 moves the contact holder 116 to the bulge of the leaf spring 112. Moderation mountain 124 by 123
The engagement piece 1 on one side of the leaf spring 109 is left in the engagement position with the next trough 127, that is, in the lighting position of the small lamp and the low beam head lamp.
12 is a hooking protrusion 11 that is next to the above-mentioned hooking protrusion 118.
9 and return independently. however,
When the transfer element 105 returns in this manner, in this case, the engagement piece 113 on the other side of the leaf spring 109 pushes the upright surface of the engagement protrusion 120 and returns it to the contact holder 116;
However, in this embodiment, the engagement piece 11 on the other side of the leaf spring 109
3 is elastically deformed on the projecting wall 114 on one side of the partition frame 106 which is constantly in a stationary state every time the transfer element 105 moves to the right in FIGS. 9 and 14 or to the left in FIG. 10. The engaging protrusion 120 is designed to ride up, and by returning from this riding position, the engaging protrusion 120
Since the contact holder 116 will not be returned to its original position, the contact holder 116 will not be returned, and this will provide support for maintaining the set state of the light control or for returning the operating lever 1 and the transfer element 105. Never. Then, when the operating lever 1 is operated forward again after returning, the engaging protrusion 119
Latching piece 1 on one side of leaf spring 109 that presses the upright surface of
12 In other words, the contact plates 130 and 132 are also changed so that the contact part 134 becomes the contact plate 139 and the contact part 135 becomes the contact plate 138 by means of the actuator 105 that can move the contact holder 116 one step further downward in FIG. To,
While the contact parts 136 are kept in contact with the contact plates 140, the contact parts 137 are changed from the contact state with the contact plate 141 to the contact state with the contact plate 142, and therefore, here, a high beam head lamp is connected to the battery electric circuit. At least this high beam headlamp is turned on instead of the aforementioned low beam headlamp. Of course, at this time, operation lever 1
While returning the transfer element 105, it is also in the neutral position.
N ₂ automatically returns to contact holder 116.
Only the bulging portion 123 of the leaf spring 122 is
The high beam headlamp is maintained in a lit state by engaging with the valley portion 128 of the final stage of No. 4. In addition, no matter how much the operating lever 1 is moved forward, the leaf spring 10 will not be attached to the contact holder 116.
There is no latch protrusion that the latch piece 112 on one side of the lever 9 presses, and not only that, but the latch piece 112 on the other side rides on the latch protrusion 121 and is disabled, so that further forward operation of the operating lever 1 is impossible. It is also considered invalid. However, if the operating lever 1 is operated rearward (downward in FIG. 3), the second rod 4
6 is moved in the opposite direction to that described above, and the transfer element 105 is also moved in the opposite direction to that described above.
Contact holder 1 in which the hooking piece 113 on the other side instead of the hooking piece 112 on one side of 09 reaches the above-mentioned high beam headlamp lighting position.
As the contact holder 116 is moved back one step upward in FIG. 12 by pressing the upright surface of the engaging protrusion 121 of No. 16, the high beam head lamp that was turned on earlier is turned off and the low beam head lamp is turned on again in its place. Daymer control is performed. Of course, the automatic return of the operating lever 1 here is carried out in the same manner as described above, although the direction is different, and after the return, the operating lever 1 is operated rearward again. However, in this case, there is no engagement protrusion on the contact holder 116 that is pushed by the engagement piece 113 on the other side of the leaf spring 109, and the engagement protrusion 119 is pushed by the engagement piece 112 on one side by forward operation of the tip of the operating lever 1. In other words, there is only the engaging protrusion 119 for switching from the low beam headlamp lighting state to the high beam headlamp lighting state. However, at this time, when the operating lever 1 is pulled out in the axial direction against the elastic force of the torsion spring 24, the second rod 46
is pushed by the slanted surface 6 of the notch 5 of the operating lever 1 and protrudes more than before as shown in FIG.
08, and the pressed auxiliary force 108 presses down the intermediate engagement piece 110 of the leaf spring 109 so that its tip faces the upright surface of the engagement protrusion 121.
Next, if the operating lever 1 is operated backward in this state, the intermediate engaging piece 110 of the leaf spring 109 will push the upright surface of the engaging protrusion 121 as the transfer element 105 is moved in the same manner as described above, and the contact holder 116 will be moved. The first
Since the head lamp is moved back one more step upward in Figure 2, the low beam head lamp is also turned off and only the small lamp is turned on. The reason why the operation is changed in this way is because there is a concern that if the operation lever 1 is simply operated backward repeatedly, the headlights may be inadvertently turned off when the car is driving at night. In short, the intention is to protect the driver or fellow passengers from danger due to careless operation. After such an operation, the operating lever 1 is automatically and immediately returned to the neutral position _N3 in the axial direction by the elastic force of the torsion spring 24, while the protrusion 4 is moved as in the previous stage.
3, 43 via the protrusions 10, 10 of the lever holder 7, the lever holder 7 is automatically and immediately returned to the neutral position _N2 in the second rotational direction by the elastic force of the compression springs 44, 44. Therefore, the second rod 46 is also returned by the elastic force of the torsion spring 48, and the driven auxiliary element 108 is returned together with the return of the engagement piece 110 of the leaf spring 109.
Furthermore, at this time, each time the operation from the previous stage is performed, the partition wall 106
The hooking piece 112 on one side of the leaf spring 109, which rides on the projecting wall 115 on the other side while being elastically deformed, touches the hooking protrusion 119, and later on the hooking protrusion 118.
will be returned beyond. Therefore, after this operation lever 1
By operating the leaf spring 10 backward once again,
The engaging protrusion 120 is attached by the engaging piece 113 on the other side of 9.
It is also possible to reliably move the contact holder 116 back upwards in FIG. 12 by pressing the upright surface of the contact holder 116, thereby turning off the small lamp and returning the light to the completely off state. Of course, in this case as well, the automatic return of the operating lever 1 is carried out in the same manner as described above, and even if the operating lever 1, which has been returned to its original position, is then operated further backwards, the contact holder 116 will not have the above-mentioned plate. Since there is no engaging protrusion that is pressed by the engaging piece 113 on the other side of the spring 109, further rearward operation of the operating lever 1 is disabled. It goes without saying that in the above-mentioned write control, the steps can be advanced or reversed not from the final step but at each step. Also, as previously mentioned, in the final stage, in the position where the high beam head lamp is turned on, by operating the control lever 1 backward, the light can be returned to the low beam head lamp lighting state. However, in order to perform such a daimer control, instead of using the normal operation described above, we made the mistake of operating the operating lever 1 in the opposite direction forward, pulling it out in the axial direction, and returning it to the neutral position N ₂ . In this case, the intermediate projecting wall 1 is attached to the partition frame 106.
If there is no 06a, there is a risk that the intermediate engagement piece 110 of the leaf spring 109 pushed out by the driving auxiliary element 108 will push the protrusion 121 and move the contact holder 116 to the position where the low beam head lamp is lit. In the case of the embodiment, the intermediate protruding wall 106a provided on the partition wall 106 reduces the protrusion of the intermediate engaging piece 110 of the leaf spring 109 and obstructs and suppresses the protrusion 121 so as to prevent it from being pushed. It is possible to prevent a so-called erroneous operation from being performed other than a normal operation.

In contrast to the above, here the operating lever 1 is torsioned into the spring 2.
When pushed in the axial direction against the elastic force of step 4,
The inner casing 101 of the second switch Y, whose passive piece 103 is pushed by the base end of the operating lever 1, includes a contact holder 116 in addition to the auxiliary actuator 108 and the actuator 105 present inside. The bulging portion 1 of the leaf spring 122 moves to the left in FIG. 5 and to the right in FIG. 12.
23 comes into contact with the small adjustment crest 129 of the adjustment ridge 124, and with the tactile sensation obtained, press the operating lever 1 at that position.
When the operation is stopped, each contact plate 130, 132 transitioning from each stage of the light control will change from the completely off state to the contact part 137 of the contact plate 132.
The high beam head lamps are turned on by changing from the contact state with the contact plate 140 to the contact state with the contact plate 144, and when the small lamps are turned on, the high beam head lamps are turned on in the same manner as described above, and the low beams are turned on. When the head lamp is turned on, the contact portion 137 is connected to the contact plate 141.
By changing the contact state from the contact state with the contact plate 144, the high beam head lamp is turned on instead of turning off the low beam head lamp, and when the high beam head lamp is turned on, the contact part 137 is connected to the contact plate 144. 142
By changing the contact state from the contact state with the contact plate 143 to the contact state with the contact plate 143, the low beam head lamp is turned on instead of turning off the high beam head lamp. On the other hand, the operation lever 1 reaches the point where the bulging portion 123 of the leaf spring 122 exceeds the small adjustment ridge 129 of the adjustment ridge 124.
When pressed, the contact portion 137 comes into contact with the contact plate 145 in all cases, and the horn sounds. Even in such a push-in operation of the operating lever 1, after the operation is released, the operating lever 1 is automatically returned to its original position by the elastic force of the torsion spring 24, and the operating lever 1 is then returned to its original position. Repeat the push-in operation and return after operation to intermittently turn on the high beam headlamp, switch the lighting between the low beam headlamp and the high beam headlamp, or make the horn sound intermittently, and use this to signal overtaking. shall be.

On the other hand, regarding the first switch X part mentioned above,
Now, when the operation button 79 here is pressed, the contact holder 60 is moved by the operation piece 81 to the right in FIG. 7 and upward in FIG.
The contact portion 67 changes from the contact state with the contact plate 92 to the contact state with the contact plate 93, and the contact plate 62 changes from the contact state with the contact portion 69.
However, due to the state of contact with the contact plate 94, the contact plate 93
and the contact plate 63 is in contact with the contact portion 72.
changes from the state of contact with the contact plate 96 to the state of contact with the contact plate 97, so that the battery current path is connected only through the flasher without going through the power switch.
A so-called hazard signal is given by connecting both small lamps for left turn signals and lighting them intermittently. When the operation button 79 is operated as described above, the operation piece 81
In addition to moving the contact holder 60, the outer casing 5
1 while elastically deforming the spring piece 83, and then the spring piece 83 restores itself to maintain the state after the operation. Therefore, the contact holder 60 also moves to the position after the movement, that is, the above-mentioned right/left turn signal. Both small lamps are kept lit intermittently. Of course, if the operating button 79 is operated in the opposite direction from this state, everything is returned to its original state, that is, both small lamps are completely turned off and maintained in that state. On the other hand, when the other operation button 86 is pressed, the contact holder 73 is moved upward in FIG. Contact plate 9 from the contact state
7, a small lamp smaller than the side marker lamp is connected to the battery circuit without going through a power switch, and a parking signal is given by lighting the small lamp. Also, at this time, the operation piece 88 moves over the spring piece 90 of the outer casing 51 while being elastically deformed, and then the spring piece 90 restores itself, thereby maintaining the state after the operation.
The contact holder 73 is also held in the position after the movement, that is, in a state in which the small lamp below the sidemarker lamp is turned on. If the operating button 86 is operated in the opposite direction from this state, everything is returned to its original state, that is, the small lamps below the side marker lights are turned off and maintained in that state.

In contrast to the above, FIGS. 16 to 21 show a second embodiment of the present invention, which basically uses the so-called rear wiper and rear washers for the rear windshield of an automobile to signal the right and left turns in the first embodiment. Furthermore, the present invention differs from the above in that the light control, daymer control, and overtaking signal are performed by driving so-called windshield wipers and windshield washers, respectively. Therefore, in FIGS. 16 to 18, 148 is the aforementioned outer casing 5.
1 is an outer casing of the first switch
53 and a contact plate 156 having a contact portion 154 and a contact portion 155 are held as a movable side together with respective elastic biasing leaf springs 157 and 158,
Further, the board 149 has contact plates 159 to 1 on the fixed side.
63 are fixedly arranged, of which contact plate 159
is connected to the motor for the rear wiper, the contact plate 160 is connected to the pump motor for the rear washer, the contact plate 161 is connected to the cam contact for returning the rear wiper, the contact plate 162 is connected to the rear washers electrical circuit of the battery, and the contact plate 163 is connected to the battery. are doing. In this case, although the operating lever 1 is not shown, in the first rotation direction, the original position corresponds to the above-mentioned right turn signal position TR, and from the next position corresponding to the neutral position _N1 to the left turn signal position. In order to be able to operate to the final stage position corresponding to TL, and to be able to maintain the position at the original position and the next stage position, and at the final stage position, after the operation is released, the next stage of the previous stage The structure is such that it automatically returns to the position shown in FIG. Therefore, with such a configuration, when the operating lever 1 is operated from the original position to the next position, the contact plate 153 becomes the contact point by moving the contact holder 150 to the right in FIG. Since the contact state of the portion 152 is changed from the contact state with the contact plate 161 to the contact state with the contact plate 163, a rear wiper motor is connected to the battery and the motor is extended to drive the rear wiper. At the operated final stage position, the first position of the contact holder 150 is
By further moving to the right in FIG. 8, the contact plate 156 changes the contact portion 154 from the position between the contact plate 159 and the contact plate 160 to the contact state with the contact plate 160, and also moves the contact portion 155 between the contact plate 161 and the contact point. Board 16
In order to change the state from the position between 2 and 2 to the contact state with the contact plate 162, a rear washer pump motor is connected to the rear washer electrical circuit of the battery, and the pump motor is extended to drive the rear washer. At this time, the rear wiper is also driven in the same manner as described above, and when the operating lever 1 is returned, the rear wiper alone returns to its original position after being driven as described above, where everything stops. On the other hand, the 19th
21, 164 is the outer casing of the second switch Y replacing the aforementioned outer casing 100, 165 is a contact holder replacing the contact holder 116, and this contact holder 165 has the hooking protrusions 117 to 121, respectively. In addition to the engaging protrusions 166 to 170, an engaging protrusion 171 is provided that is aligned with the engaging protrusion 169 of the engaging protrusions 169 to 170, so that the driving auxiliary element 108 is omitted from the moving element 105, and in other words, the operation of pulling out the operating lever 1 is made unnecessary. ing. Further, the contact holder 165 has a contact plate 174 having a contact part 172 and a contact part 173, a contact plate 177 having a contact part 175 and a contact part 176, and a contact plate 180 having a contact part 178 and a contact part 179 on the movable side. In this case, contact plates 184 to 190 on the fixed side are fixedly arranged on the inner surface of the outer casing 164, of which the contact plates 184 to 190 are fixed. The plate 184 is on the high speed side of the front wiper motor, the contact plate 185 is on the low speed side of the motor, the contact plate 186 is on the battery, the contact plate 187 is on the cam contact for returning the front wiper,
The contact plate 188 is connected to the intermittent actuator connected to the front wiper motor, the contact plate 189 is connected to the front washer pump motor, and the contact plate 19
0 is connected to the battery's intermittent wiper and front washer electrical circuits, respectively. Further, in this case, a moderation crest 191 replacing the above-mentioned moderation ridge 124 is formed narrower than the moderation ridge 124 so that the pushing operation of the operating lever 1 can be stopped at one stage. Therefore, with such a configuration, if the operating lever 1 is operated once forward in the second rotation direction, the contact holder 165 is moved to the second position by the feeder 105 as described above.
1, in each step that is advanced one step downward in FIG. By changing the contact state of the portion 176 from a non-contact state to a contact state with the contact plate 188, an intermittent actuator is connected to the battery's intermittent wiper electric circuit, and the intermittent actuator is connected to the front wiper motor connected to the intermittent wiper electric circuit. The wiper is driven intermittently, and then the contact plate 174 moves the contact part 172 from the contact state with the contact plate 187 while keeping the contact part 173 in contact with the contact plate 185.
86, the low speed side of the front wiper motor is connected to the battery, the motor is extended to drive the front wiper at low speed, and finally the contact plate 174 brings the contact portion 172 into contact with the contact plate 186. By changing the contact portion 173 from the state of contact with the contact plate 185 to the state of contact with the contact plate 184 while the contact portion 173 is in contact with the contact plate 185, the high speed side of the front wiper motor is connected to the battery, and the motor is extended to drive the front wiper at high speed. urge Of course, if the operating lever 1 is operated backwards from the state where the final stage has been reached or at each stage before reaching the final stage, the contact holder 165 will also move backward in the same manner as described above. Each of the above steps is sequentially returned to the previous step according to the
Particularly in the case of this second embodiment, even when returning from the last stage state to the previous stage state, this can be done simply by repeatedly operating the operating lever 1 backward, that is, by engaging the contact holder 165. Protrusion 16
The reason why the engaging protrusion 171 is provided in addition to the above-mentioned light control is that the object to be operated is a wiper control, which is not dangerous. In response to the above, when the operating lever 1 is pushed in the axial direction, the contact holder 165 is held in the position moved to the right in FIG. 21 while the operating state is maintained. No matter which stage the contact plate 180 is in, the contact portion 178
In addition to contacting the contact plate 190, the contact portion 1
79 is brought into contact with the contact plate 189, thereby connecting the front washer pump motor to the front washer electrical circuit of the battery, which in turn drives the front washer.

Incidentally, in both the first and second embodiments described above, in the first embodiment, only the light control and the dimer control are directly related to the present invention, and in the second embodiment, the front wiper drive is directly related to the present invention. However, since the present invention can be widely applied to devices other than automobile lever switch devices or other switch devices, the objects to be controlled may also include the above-mentioned light control, dayr control, or front wiper drive. It is not limited. Furthermore, even if these controls are carried out, the light control may omit the dayr control, and the front wiper drive may be carried out without intermittent operation. It is sufficient that the state can be changed by performing stepwise motion in at least three stages.

As is clear from the foregoing, the present invention provides an actuator that is provided to move in at least three stages in each reciprocating manner on a predetermined board surface, and that has engaging protrusions arranged in rows in each direction of movement in both reciprocating directions. , a reciprocating reciprocating unit which is provided to move on the actuator in the same direction as the actuator, and by its movement engages and pushes the engaging protrusion that is in the direction of movement and moves the actuator to the next position. a transfer element having respective engagement pieces for the transfer element; and a transfer element provided on the side of the transfer element on which the engagement pieces exist and at a position adjacent to the engagement protrusion, and which maintains a stationary state when the transfer element moves. a protruding wall for each reciprocation, for elastically allowing one of the reciprocating engaging pieces opposite to the movement direction to ride over the engaging protrusion; The actuator is equipped with a biasing means that applies a force to automatically return to the original position before movement, so that only the actuator moves forward one step by a single movement operation accompanied by automatic return of the actuator. Alternatively, it is possible to reliably change the state by a stepwise operation in which the actuator is moved backward and held in the forward or backward position, and the complicated operation can also be performed by returning the actuator to be held in the forward or backward position. It is possible to provide a stepping mechanism that exhibits truly excellent effects, such as smooth movement without causing problems such as the return of the slippery transfer element being inhibited.
