(B) Conventional technology An automobile has a plurality of windows (windows), and in order to individually open and close them electrically, a plurality of switch buttons for opening and closing are required corresponding to the number of windows.

In this case, it is necessary for an operator (for example, a driver) to clearly understand which switch corresponds to the window of which seat among the plurality of switch buttons. This is because, for example, the driver may operate the switch button in order to open and close the window during driving, so that the judgment can be made instantly.

Therefore, as shown in FIG. 2 which will be described later, it is preferable that one switch button is associated with one window and the arrangement of the switch buttons is also associated with the arrangement of the windows.

By the way, the above switch button is
Push down and do both directions of triggering,
As described above, since the driver may open and close the window during driving, it is preferable to increase the size of the switch buttons and the space between the switch buttons to some extent in consideration of operability.

For example, a push-button switch that only pushes can be configured with a minimum required area that only pushes, but a switch button that performs a bidirectional operation in which a trigger operation is added to a push-down operation. In this case, in order to smoothly operate the finger when it is raised, as described above, it is preferable to increase the space between the switch buttons and the switch buttons to some extent.

However, this technical idea causes a problem that the size of the vehicle power window switch increases.

On the other hand, since the external dimensions of the car body are fixed,
Since the space inside the vehicle is also limited and the power window switch must be installed in the limited space, downsizing of the in-vehicle power window switch occurs as another problem contradictory to the above-mentioned upsizing. To do.

The above-mentioned operating rod 53 projects between the two slider shafts 55, 55 by projecting to the upper surface of the switch unit 54.
The lower end of the slider is inserted, and one slider shaft 55 is operated to switch by swinging the operating rod 53 based on the operation of the switch button 52 described above.

However, when configured as described above, the switch unit
Since the slider shafts 55, 55 are projected on the upper surface side of 54,
There is a problem in that the protrusion amount H becomes bulky and the vertical direction of the switch cannot be made compact and compact.

(C) Problem to be Solved by the Invention An object of the present invention is to provide a vehicle-mounted power window switch that can be formed in a compact size as a whole without impairing the operability of each switch button corresponding to the arrangement of windows. .
