[Detailed description of the invention]

[0001]

The present invention relates to a first switch element and a second switch element which are switched based on the operation of a first operation knob.
And a second switch element that is switched based on the operation of the operation knob.

[0002]

2. Description of the Related Art For example, in a motor vehicle, a switch device for controlling a motor of an electric mirror in which the directions of outer mirrors provided on left and right doors are adjusted by a motor has the following structure. (See, for example, Japanese Utility Model Application No. Hei 1-35718).

That is, a first operation knob that can swing in four directions is provided on a switch body, and is pressed on a wiring board provided in the switch body based on the swing operation of the first operation knob. For example, an elastic member made of, for example, silicon rubber having a plurality of elastically deformable contact holders for switching the operation switch is disposed. Also, the first
A second operation knob is slidably provided in the opening formed at the center of the operation knob, and is slid on the wiring board by sliding operation of the second operation knob on the wiring board. A configuration is provided in which a contact holder for switching the changeover switch is provided.

Thus, in the above-described configuration, one of the left and right mirrors is selected by sliding the second operation knob to switch the changeover switch, and the first operation knob is rocked. By operating the operation switch to switch the direction of the mirror on the selected side up, down, left and right.

[0005]

By the way, in this type of switch device, when the second operation knob is slid, the contact holder hits the switch body and a relatively loud collision sound is generated. .

In order to cope with this point, it is conceivable to attach a cushion rubber to alleviate the collision noise to, for example, one of the end of the contact holder and the corresponding switch body.

However, in the case of such a configuration, the operation sound at the time of sliding operation of the second operation knob can be reduced. However, since a cushion rubber is separately required, the cushion rubber is required. There are disadvantages that the number of parts increases, the assembling becomes troublesome, and the cost increases.

[0008] Therefore, an object of the present invention is to provide a switch device capable of reducing operation noise without increasing the number of parts and thereby reducing costs.

[0009]

According to the present invention, there is provided a switch device comprising: a switch body; a board provided inside the switch body; a first operation knob provided to be pushed into the switch body; An elastic member disposed on the substrate, the elastic member having an elastically deformable contact holder that is pressed based on a pressing operation of the first operation knob to switch the first switch element; A second operation knob provided in the vicinity thereof, and a contact slidably disposed on the substrate and sliding on the substrate based on operation of the second operation knob to switch a second switch element. A holder, wherein the elastic member is provided integrally with a buffering portion which is in contact with the contact holder at a sliding end position of the contact holder.

[0010]

According to the above-mentioned means, when the contact holder is moved to the sliding end position by the second operation knob, the contact holder comes into contact with the buffer portion, so that the collision noise can be reduced. In this case, the number of components does not increase because the buffer portion is provided integrally with the elastic member.

On the other hand, the first and second operation knobs 26 and 4
When the second operation knob 40 is slid to the right in a state opposite to that described above in a state in which the contact holders 0 are both held at the neutral position, the contact holder 44 slides to the right via the lever 43, Accordingly, each of the slide switches 46 to 48 of the changeover switch 49 is switched to the right side in FIG. 8 and the state is maintained. As a result, the right mirror motors 56 and 57 are selected.

At this time, when the contact holder 44 moves to the right sliding end position, the right end of the contact holder 44 comes into contact with the right buffering portion 16 of the elastic member 13 as in the case described above. The collision sound at that time is reduced.

When the four operation parts (symbols 29a to 29d) of the first operation knob 26 are depressed while the second operation knob 40 is operated to the right, the left mirror is operated. Except that the motor for vertical adjustment 56 of the right mirror is selected instead of the motor 54 for vertical adjustment, and the motor 57 for right and left adjustment of the right mirror is selected instead of the motor 55 for left and right adjustment of the left mirror. Since the operation is the same, the description is omitted.

On the other hand, in the above-described configuration, for example, when water is applied to the first operation knob 26 and the water enters the inside through the opening 29 in the center, the water is
As shown by the arrow B in FIG. 2, the water flows along the outer surfaces of the operation portion 41 and the eave portion 42 of the second operation knob 40, and flows out of the drain hole 36 formed in the holder 28 of the first operation portion 26. Then, the gas is discharged to the outside of the switch body 1 through the cutout concave portion 7 and the openings 5a and 5b formed in the partition portion 2 of the switch body 1.

When water enters the switch body 1 from the periphery of the first operation knob 26, the water passes through the notch 7 of the partition 2 and the openings 5a, 5b. 1 will be discharged to the outside.

Therefore, even if water is applied to the first operation knob 26, it is possible to reliably prevent the water from entering the contact holder 44 and the contact holder 15 side.

By the way, in such a switch device, the four variable hinge portions 34 of the first operation knob 26 are generally provided at four corners of the first operation knob 26. However, the variable hinge portion 34
Are provided at the four corners of the first operation knob 26, if the outer shape of the first operation knob 26 is slightly changed due to a design change or the like, each of the variable hinge portions 34 is changed.
Since the distance between them changes, the first operation knob 26
Therefore, there is a situation that the stroke amount of the contact holder 15 and the elastic deformation amount of each contact holder portion 15 in the elastic member 13 must be examined each time.

In this regard, in the case of the present embodiment, the four variable hinge portions 34 of the first operation knob 26 are provided not at the corners but at portions slightly closer to the center. Even if the outer shape of the first operation knob 26 is slightly changed in the left-right direction due to a change in design or the like, the distance between the variable hinge portions 34 does not need to be changed. Therefore, the stroke amount of the first operation knob 26 and the elastic member 1
There is an advantage that it is not necessary to consider the amount of elastic deformation and the like of each contact holder portion 15 in 3 each time.

[0041]

As is apparent from the above description, according to the present invention, when the contact holder is moved to the sliding end position by the second operation knob, the contact holder comes into contact with the buffer. Therefore, the collision sound, that is, the operation sound can be reduced. In this case, the buffer portion is provided integrally with the elastic member having the elastically deformable contact holder portion that is pressed based on the pressing operation of the first operation knob, so that the number of components does not increase. Therefore, the operation sound can be reduced without increasing the number of parts, and the cost can be reduced.
