As a result, the current flow is 29a→24-→33→M
→ 30 → 24 → 31, and as a result, the motor M for driving the window regulator is driven in the reverse direction, and the window is lowered and opened.

Then, by releasing the operating force of this switch button, the movable contact 24 integrated with the slider 25 returns to its original OFF position.

As mentioned above, during non-switching operation, the pair of left and right sliders 25 corresponding to the two sets of contact patterns P1 and P2
．． 25 is biased and moved to the OFF position, and from this state, when one slider 25 is slid in the opposite direction through the slider operation rod 21, the contact of the ON position on the positive side changes from the OFF position. When the contact state is switched to the corresponding state and the other slider 25 is slid to the anti-biasing side, the contact state is similarly switched from the OFF position to the ON position on the opposite polarity side.

Therefore, during the switching operation, the switching operation can be performed by selecting the contact corresponding side of either the positive or reverse polarity ON position from the neutral OFF position, which is easy to operate.

By the way, each of the plurality of switch units 22 described above has each switch button 14.1 exposed on the upper surface of the operation cover 12.
5, 16, and 17 respectively, the performance of the above-mentioned switch unit 22 can be checked individually during the assembly of the on-vehicle power window switch 11.

As a result, in the event of a defect, it is possible to deal with it by only replacing parts, and there is no need to replace the entire switch as in the past, which significantly reduces manufacturing losses and costs. There are effects that can be done, and in addition,
It is also possible to omit performance confirmation after assembly is complete.

In the correspondence between the configuration of the present invention and the above-described embodiments, the contactor of the present invention corresponds to the movable contactor 24°24 of the embodiment, and similarly, the contact patterns are the first contact pattern P1 and the first contact pattern P1. Although the present invention corresponds to the two-contact pattern P2, it is not limited to the configuration of the above-described embodiment.
