DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device provided with an operation knob rotatably provided on a switch body and rotated from a reference position.

[0002]

For example, in agricultural machines such as a combine and a tractor, the operation of a rotary knob (operation knob) for turning on a light is different from each other. For example, as shown in FIG.
Turning the rotary knob 1 to the left with the "FF" as the reference position indicates "head (headlight ON)", and turning to the right indicates "work light (work light ON)".

As shown in FIG. 9, in a tractor,
When the rotary knob 2 is rotated one position to the left with “OFF” as the reference position, “Head Lo (headlight L
o: ON) ", and further turning left by one position becomes" Head Hi (headlight Hi: ON) ".

[0004] Therefore, the arrangement of the tact switches that are turned on at each operation position differs in each model.
Conventionally, a board for a switch has been created for each model. Therefore, the production cost of the substrate is required according to the number of models.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a switch that can set a plurality of rotation patterns from a reference position of an operation knob while sharing a switch substrate. It is to provide a device.

[0006]

An operation knob having a portion, and by selecting storage of the decelerator in a plurality of storage portions of the operation knob, the operation knob is moved from a reference position. Characterized in that it is capable of setting the dynamic pattern in a plurality.

With this configuration, when the detent stored in the storage part is engaged with the detent hole of the plate at the rotation position in accordance with the rotation of the operation knob, the detent is inserted through the through hole of the switch body. The operator of the corresponding push switch is pressed. Therefore, by selecting storage of the moderator in a plurality of storage sections, a plurality of rotation patterns of the operation knob from the reference position can be set. And, for example, by using different substrates such as a light switch of a conban in or a tractor, it is possible to cope with those having different rotation patterns from the reference position by using a substrate provided with a push switch in common. .

In this case, as described in claim 2, the switch body and the operation knob are provided with stoppers respectively engaging with each other to regulate the rotation range of the operation knob, and one of the switch body and the operation knob is connected to the switch body and the operation knob. It is preferable to select from a plurality of stoppers having different positions of the stoppers according to a plurality of rotation patterns of the operation knob.

With this configuration, when the rotation pattern of the operation knob is different, one of the switch body and the operation knob is appropriately selected from a plurality of switches, so that the operation knob can be adjusted according to the different rotation pattern. Can be restricted.

(C) is a case where the present invention is applied to a combine as described above.

FIG. 1A shows that the light is "O" as a reference position.
At this time, the indicating portion 33e of the rotary knob 33 indicates "OFF", so that the position of the storage portion 34 matches the moderation hole 29f of the plate 28, and the moderation ball 37 Are engaged with the moderation holes 29f, and provide moderation at the "OFF" operation position.

From this position, the user operates the rotary knob 33.
When the rotary knob 33 is gripped and turned to the positive (left) side by aligning the fingers with the knob recesses 33d, 33d, the moderation ball 37 is released from the state of being engaged with the moderation hole 29f to remove the surface of the plate 28. Move to the positive side while sliding.

Then, as shown in FIG. 1 (b), when the rotary knob 33 is turned to the positive side by 30 degrees, the position of the storage portion 34 matches the moderation hole 29c of the plate 28, and the moderation ball 37 is The tactile switch 13c is turned on by pressing the operation element from above the rubber cover 18c through the through hole 25c of the switch body 20 while engaging in the moderation at the "head" operation position by being engaged with the hole 29c.

A plurality of rotation patterns from the reference position of the rotary knob 33 can be set. In addition, even when the rotation pattern from the reference position is different due to a different application such as a light switch 43 of a tractor or a tractor, the substrate 12 on which the tact switches 13c and 13d are provided is commonly used. It becomes possible. Therefore, unlike the related art, it is not necessary to create each board in which the arrangement of the switches is changed, and the cost can be reduced.

Further, according to the present embodiment, the rotary knob 3
3 is provided with a stopper 34a, and a light switch 43
Is used for the combine, the switch body 20 provided with the stoppers 26 and 27 in the recess 23a is used, and when it is used for the tractor, the stoppers 26 'and 27' are provided at different positions of the recess 23a. Since the switch body 20 'is used, the rotary knob 3
3 have different rotation patterns, the switch body 2
By appropriately selecting 0 and 20 ', the rotation range of the rotary knob 33 can be regulated according to the different rotation patterns.

The present invention is not limited to the embodiment described above and shown in the drawings, but can be modified or expanded as follows. The stopper is not limited to being provided at a different position on the switch body side depending on the application, and a stopper on the operation knob side may be provided at a different position. Further, the stopper may be appropriately provided as needed. As shown in FIGS. 6 (a) and 6 (b), the plate may be provided in common with notches corresponding to different stopper positions of the switch body in advance. The push switches are not limited to the tact switches 13a to 13d, but may be other push switches.

The operation position from the reference position is not limited to two, but may be applied to a position having three or more operation positions. The moderator is not limited to the moderator ball 37. For example, a conical moderator may engage with the moderator hole. The urging means such as a spring is not limited to urging the moderator, and the urging means and the moderator may be integrally formed. The application is not limited to the one applied to the light changeover switch, and is not limited to the one applied to an agricultural machine such as a combine or a tractor. The present invention may be applied to passenger cars and other vehicles, and is not limited to vehicles. In short, according to the difference in use, the operation knob can be applied as long as a plurality of rotation patterns can be considered from the reference position.

The following effects are obtained. According to the switch device of the first aspect, the detent stored in the storage portion is engaged with the detent hole of the plate at the rotation position in accordance with the rotation of the operation knob, through the through hole of the switch body. Since the operator of the corresponding push switch is pressed, by selecting storage of the moderator in a plurality of storage sections, a plurality of rotation patterns of the operation knob from the reference position can be set. And, for example, a light switch of a convenin or a tractor, which has a different application and a different rotation pattern from a reference position, can be coped with by using a substrate provided with a push switch in common. Creation costs can be reduced.

According to the switch device of the second aspect, when the rotation pattern of the operation knob is different, one of the switch body and the operation knob is appropriately selected from a plurality of switches, so that the switch body can respond to the different rotation pattern. Thus, the rotation range of the operation knob can be regulated.
