DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a wiper switch of an automobile will be described below with reference to FIG.

FIG. 1 shows a cross section of the entire structure. In FIG. 1, a wiper knob 12 as a first operation member and a washer knob 13 as a second operation member are pushed into a main body case 11 having an open upper surface. It is operably arranged.

The wiper knob 12 operates a wiper switch 14 as a first switch, and a lower end portion thereof is integrally formed with a contact portion 12a and a receiving portion 12b extending below the washer knob 13. . A return spring 15 serving as a first spring is provided between the lower surface of the contact portion 12 a of the wiper knob 12 and the center of the inner bottom surface of the main body case 1.
Is provided, and the wiper knob 12 is biased upward to be held at the return position.

The wiper knob 12 is provided with a lock mechanism 18 comprising a cam portion 16 and an engagement pin 17. The wiper knob 12 is pressed downward to move the wiper switch 14 to the lock position after the wiper switch 14 is operated. Then
The lock mechanism 18 holds the wiper knob 12 at the lock position. When the wiper knob 12 is pressed again, the lock mechanism 18 is released and returns to the return position by the urging force of the return coil spring 15. .

In this case, when the wiper knob 12 is pressed, the lock mechanism 18 moves the engagement pin 17 along the left cam groove of the cam portion 16, and the pressing operation force on the wiper knob 12 at the lock position. Is released, the engagement pin 1
7 is locked by the top portion 16a of the cam portion 16, so that the wiper knob 12 is prevented from returning to the return position by the urging force of the return coil spring 15. When the wiper knob 12 is pressed again, the engagement pin 17 is moved to the cam portion 16.
Along the right cam groove and can be moved to the return position.

The washer knob 13 is for operating a washer switch 19 as a second switch, and has a lower end portion integrally formed with a contact portion 13a extending toward the wiper knob 12. And this washer knob 13
The contact portion 13a is the contact portion 12a of the wiper knob 12.
The return coil spring 20 as a second spring is disposed between the lower end surface and the receiving portion 12b of the wiper knob 12.

As a result, when the wiper knob 12 is at the return position, the washer knob 13 is
When the wiper knob 12 is held at the lock position by the return coil spring 15, the return coil spring 15 holds the wiper knob 12 at the return position by the urging force of the return coil spring 20.

In the above configuration, when the wiper knob 12 is pressed in a state where the wiper knob 12 and the washer knob 13 are both at the return position (the illustrated position), the wiper knob 12 resists the urging force of the return coil spring 15. The wiper switch 14 is actuated.

At this time, as the wiper knob 12 moves downward, the receiving portion 12b for receiving the return coil spring 20
Moves downward, but since the return coil spring 20 extends and exerts its urging force upward, the washer knob 13 is held at the return position.

Next, with the wiper knob 12 held in the locked position by the lock mechanism 18, the washer knob 1
When the button 3 is pressed downward, the washer knob 13 moves downward against the urging force of the return coil spring 20, and the washer switch 19 is operated.

In this case, the moving distance of the washer knob 13 is set so that the washer switch 19 is operated but cannot be moved until the contact portion 13a contacts the contact portion 12a of the wiper knob 12 at the lock position. Is set. Therefore, when the operation pressing force on the washer knob 13 disappears, the washer knob 13 alone returns to the return position by the urging force of the return coil spring 20.

When the washer knob 13 is pressed while the wiper knob 12 is held at the return position, the contact portion 13a of the washer knob 13 is
2 is in contact with the abutting portion 12a, the washer knob 13 is moved together with the wiper knob 12 against the urging force of the return coil spring 15, whereby the wiper switch 14 and the washer switch 19 are moved. Is activated.

Since the relative positions of the washer knob 13 and the wiper knob 12 do not change at this time, the operation is independent of the biasing force of the return coil spring 20. Also,
At this time, since the moving distance of the washer knob 13 is set as described above, the wiper knob 12 operates the wiper switch 14 but does not reach the lock position. Therefore, when the pressing operation force on the washer knob 13 is lost, both the wiper knob 12 and the washer knob 13 return to the return position by the urging force of the return coil spring 20.

According to this embodiment, the wiper knob 12 and the washer knob 13 have the three
In any one of the two operation modes, the operation pressing force may be exerted against the urging force of any one of the return coil springs 15 and 20, so that the urging force of these return coil springs 15 and 20 may be applied. If the spring constant is set so that is substantially the same, the user can always perform the operation with the same operation force, and the operation feeling is improved.

In the above embodiment, the first and second operation members are connected to the wiper knob 12 and the washer knob 1.
However, the present invention is not limited to this, and the present invention can be applied to all switch devices having the above three combinations of operation modes.
