The return force (biasing force) of each dome 8 in the second switch 5 and the second switch 6 is set to be the same. Although not shown, the signals of the first and second switches 5 and 6 are output to a control device including a microcomputer.

On the lower side of the switch body 2, 1
A pusher 11 (see FIG. 5) in the form of a rectangular plate is provided. The pusher 11 is provided with four dome portions 8 in the first and second switches 5 and 6 for down and up. Are arranged so as to straddle the upper surface of the. On the lower surface of the pusher 11, four hemispherical convex portions 11a are provided corresponding to the respective dome portions 8, and on the upper surface, each of the first switch 5 for down and the up is provided. The concave receiving portions 12a and 12b are provided at the biased positions. The switch body 2 includes the receiving portions 12a,
Insertion holes 13 and 13 are formed in a portion corresponding to 12b.

The lower surface of the operation knob 1 has an insertion hole 13,

a and 12b, and the receiving portions 12a and 12b are set so as to be located at positions biased toward the respective first switches 5 for down and up as described above. The operation knob 1 is covered with a cover 15.

Next, the operation of the above configuration will be described. When the operation knob 1 is not operated, as shown in FIGS. 1A, 3 and 4, each movable contact 9 in the first and second switches 5, 6 for down and up is a fixed contact. 10 and the first and second switches 5 and 6 are off. The operation knob 1 is held at the original position by the urging force of each of the first and second switches 5 and 6 for down and up above the respective dome portions 8.

In this state, when the operation knob 1 is rotated in the direction of arrow A (see FIG. 3), for example, the down direction,
In FIG. 3, the left receiving portion 12a of the pusher 11 is pressed by the left pressing portion 14a.
Down first and second switches 5 on the left side
6, the two dome portions 8 are pressed.

At this time, the pressing portion 1 against the pusher 11
Since the pressed position of 4a is set to a position deviated to the first switch 5 side of the down first and second switches 5, 6, the first and second switches 5, 6 are set. Of the two dome portions 8, the dome portion 8 of the first switch 5 is strongly pressed and elastically deforms (see FIG. 1B).

When the operation knob 1 is rotated to the first operation position as shown in FIGS. 1B and 6, the movable contact 9 of the first switch 5 is moved to the corresponding fixed contact 10 And the first switch 5 is turned on. Based on this, the window glass (not shown) is moved in the down direction. In this case, the window glass is moved in the down direction only while the first switch 5 is on. At this time, the dome portion 8 on the second switch 6 side is also pressed downward via the pusher 11, but the dome portion 8 does not deform until the movable contact 9 contacts the corresponding fixed contact 10; The second switch 6 remains off.

When the turning operation force on the operation knob 1 is released from the state shown in FIG. 1B, the dome portions 8 of the first and second switches 5 and 6 return to their original positions. , The first switch 5 is turned off, and the pusher 11 is turned off.
Then, the operation knob 1 is returned to the original position via the pressing portion 14a.

When the operation knob 1 is rotated farther in the direction of arrow A than the first operation position, the second operation shown in FIG.
When the dome portion 8 of the first switch 5 is pressed through the pressing portion 14a and the pusher 11 to be elastically deformed, the first switch 5 is turned on. At the same time, the dome portion 8 of the second switch 6 is also pressed and elastically deformed, so that the second switch 6 is also turned on.

As described above, once the second switch 6 is turned on, even if the operation force on the operation knob 1 is released and the first and second switches 5 and 6 are turned off, the window glass remains at the maximum. It will be automatically moved to the lower position.

When the operation knob 1 is turned in the direction of arrow B, which is the up direction, contrary to the above, the movement is substantially the same as that described above, though not shown. That is,
When the operation knob 1 is rotated in the direction of arrow B from the non-operation state of the operation knob 1, the right receiving portion 12b of the pusher 11 is pressed by the right pressing portion 14b in FIG. , The two dome portions 8 of the right first and second switches 5 and 6 are pressed.

Also at this time, the pressing position of the pressing portion 14b against the pusher 11 is set to a position deviated toward the first switch 5 of the first and second switches 5 and 6 for raising. Therefore, of the dome portions 8 of the first and second switches 5 and 6, the dome portion 8 of the first switch 5 is strongly pressed and elastically deforms (FIG. 1B).
reference).

When the operation knob 1 is turned to the first operation position in the direction of arrow B, the movable contact 9 of the first switch 5 comes into contact with the corresponding fixed contact 10 and the first switch 5 is turned on. Is turned on. Based on this, the window glass (not shown) is moved in the up direction. Also in this case, the window glass is moved in the up direction only while the first switch 5 is on. At this time, the dome portion 8 on the second switch 6 side is also pressed downward via the pusher 11, but the dome portion 8 does not deform until the movable contact 9 contacts the corresponding fixed contact 10. , The second switch 6 remains off.

When the operation force on the operation knob 1 is released from the state in which the operation knob 1 is turned to the first operation position, the respective dome portions of the first and second switches 5 and 6 are released. 8 returns to the original position, the first switch 5
Is turned off, and the pusher 11 and the pressing portion 14
The operation knob 1 is returned to the original position via b.

When the operation knob 1 is rotated farther in the direction of arrow B than the first operation position and is operated to the second operation position, the first knob is pushed via the pressing portion 14b and the pusher 11 to the first operation position. As the dome portion 8 of the switch 5 is pressed and elastically deformed, the first switch 5 is turned on, and the dome portion 8 of the second switch 6 is also pressed and elastically deformed. The second switch 6 is also turned on (see FIG. 1C).

As described above, once the second switch 6 is turned on, even if the operating force on the operation knob 1 is released and the first and second switches 5 and 6 are turned off, the window glass is kept at the maximum. It is automatically moved to the upper position.

According to the first embodiment, the following effects can be obtained. First, the means for returning the operation knob 1 to the original position is a means for returning the movable contacts 9 of the first and second switches 5 and 6 from the fixed contact 10 by applying the urging force of the two dome portions 8 as the return means. Because it uses, unlike the conventional that required an indenter and a compression coil spring,
No dedicated return means for returning the operation knob 1 to the original position is required. In addition, when the operation knob 1 is rotated, one of the two dome portions 8 is elastically deformed, and both the dome portions 8 are elastically deformed. A sense of moderation can be obtained.

Further, only one pusher 11 for pressing each dome portion 8 of the first and second switches 5 and 6 is provided for each of the four switches. Unlike the conventional case that requires four pushers, the number of pushers 11 can be greatly reduced.

Therefore, the number of parts can be greatly reduced, and accordingly, productivity can be improved and cost can be reduced.

FIG. 7 shows a second embodiment of the present invention. The second embodiment differs from the first embodiment in the following points. That is, for example, the thickness of the skirt-shaped elastically deformable portion 20a of the dome portion 20 constituting the return means on the first switch 5 side of the first and second switches for down 5 and 6 is set to the second thickness. The thickness of the elastically deformable portion 21a of the dome portion 21 constituting the return means on the side of the switch 6 is set smaller than the thickness of the elastically deformable portion 21a, whereby the urging force of the dome portion 20 on the first switch 5 side is reduced. Is set to be smaller than the urging force of the dome portion 21 on the switch 6 side.

The receiving portions 12a, 12a of the pusher 11
b (only one receiving portion 12a is shown in FIG. 7)
And the second switches 5 and 6 are formed substantially at the center, and the insertion holes 13 and 13 of the switch body 2 are formed corresponding to the receiving portions 12a and 12b. The parts 14a and 14b (also shown in FIG.
Only one pressing portion 14a is shown).
The operation knob 1 is formed substantially at the center of the lower surface of the operation knob 1 corresponding to the positions a and 12b.

In the second embodiment having such a structure, the same operation and effect as those of the first embodiment can be obtained.

The present invention is not limited to the above embodiments, but can be modified or expanded as follows. The first and second switches 5, 6 are shown in FIG.
Instead of providing one pair on each of the right and left sides, a configuration in which only one pair is provided on one side may be adopted. Further, in the case of such a configuration, the operation knob 1 may be configured to reciprocate up and down linearly instead of rotating. In addition, it is needless to say that the present invention can be applied to switch devices other than the power window switch device.

[0033]

As is apparent from the above description, according to the present invention, the number of parts can be reduced in a configuration in which a two-stage switch operation is performed by operating the operation knob in one direction. Accordingly, the productivity can be improved and the cost can be reduced.
