Description

[Detailed description of the invention] [Field of industrial application] The present invention is a composite switch in which a single operating knob is configured to be capable of swinging and pressing operations, and different switch sections can be switched in each operating mode. It is related to.

In particular, the present invention provides a switch that is useful as a switch for controlling the operation of a rear wiper device and a washer device installed in the rear window of an automobile.
The present invention relates to a compound switch in which a single operating knob can be used, for example, to change the speed of a rear wiper device by swinging, and to operate a washer device by pressing.

[Conventional technology]

Conventionally, switches that control the operation of multiple related devices, such as the rear wiper device and washer device installed in automobiles, were developed in 1982 in consideration of ease of operation and reduction of the area occupied by the instrument panel. The switch configuration was disclosed in Japanese Patent No. 59426.

That is, the switch disclosed in the above-mentioned publication had a so-called parent-child switch structure in which a press switch having an independent switch function was incorporated into the operation knob of the swing operation switch whose switch portion was switched by swing operation.

[Problems that this invention attempts to solve]

As described above, the conventional switch has a configuration in which the operating knob of the other switch section protrudes from the operating surface of the operating knob of one switch section. Therefore,
Conventional combination switches have complicated structures, are difficult to assemble, cannot be miniaturized, and are unstable in operation.
There were various problems such as high costs. Furthermore, since the conventional switch has a structure having two independent operation knobs, the operator has to select one of the operation knobs, and the switch cannot be said to have good operability.

The present invention was devised to solve the above-mentioned conventional problems, and a single operating knob is configured to be able to operate in two modes: rocking motion and pressing operation, and the single operating knob can be used in two modes. It is an object of the present invention to provide a composite switch with good operability that allows switching of switch parts.

Furthermore, another objective is to provide a composite switch that has a simpler structure than conventional composite switches, has good assembly and operability, can be easily miniaturized, and can reduce costs. purpose.

Furthermore, since the compound switch has the above-described configuration, the lamp 432 for illumination can be placed at the lower center of the operating knob 2.

Next, the operation of the above compound switch will be explained.

First, the swing motion will be explained.

Move the operating knob 2 from the position shown in Figures 1 and 4.
When the operating knob 2 is swung in the _S1 direction or the _S2 direction, the operating knob 2 is swung around the shafts 23a and 23a,
In addition, it is held at a predetermined swinging position by a moderation mechanism consisting of a moderation ridge 25a provided on the hanging piece 25 and a steel ball 318c biased by a coil spring 318b. The operating knob 2 linearly moves the arm portion 412a of the movable body 412 inserted into the elongated hole 24a of the hanging piece 24 by its swing. That is, the movable body 412 moves in conjunction with the swinging of the operation knob 2.
slides on the pole plate 4, and the fixed contact piece 4 of the pole plate 4
11 and movable contact pieces 414a, 414 of the movable body 412
b is brought into contact and separated, and the first switch portion 41 is operated.

Next, the pressing operation will be explained.

When the operating knob 2 is pressed in the P direction from the position shown in FIG. 2, the inner case 3 moves in the direction of the pole plate 4 in conjunction with the operating knob 2 while elastically deforming the return springs 315, 315. The movement of the inner case 3 causes the movable body 423 of the second switch portion 42 to move in the right direction in FIG. 4 via the operating rod 316. Due to the movement of the movable body 423, the fixed contact piece 422 provided in the groove 421 and the movable body 4
A movable contact piece 425 disposed at 23 moves toward and away from the movable contact piece 425, thereby operating the second switch portion 41.

Further, in the pressing operation, when the pressing operation of the operation knob 2 is released, the inner case 3 returns to the original position shown in FIG. 4 by the elastic force of the return springs 315, 315. As the inner case 3 moves back, the movable body 423 also returns to its original position due to the elastic force of the coil spring 426.

Furthermore, the above-described pressing operation is not only movable no matter which swing position the operating knob 2 is in, but also the operating knob 2 can be operated in a swinging manner while being pressed. In other words, the combined switch allows one operation knob 2 to operate different loads, for example, a rear wiper device and a washer device, at the same time.

Next, the lighting section 43 is used as a night light or an operation indicator. For example, when the compound switch is used as a switch for controlling the operation of a rear wiper device and a washer device for an automobile, it is used as a night light or an operation indicator. Used for lighting.

[Second example]

The second embodiment of the composite switch according to the present invention is shown in the fifth embodiment.
This will be explained based on the diagram and FIG.

Since the composite switch of this embodiment has the same structure as the first embodiment described above except for the second switch section 42, only the structure of the second switch section 44 will be described here.

The second switch part 44 has a fixed contact 443 in a recess 441 bored in an appropriate part of the pole plate 4, and a movable contact 444 that is elastically pressed by the fixed contact 443.
It consists of a plate spring contact piece 444 with a. Further, on one side of the recess 441, the recess 441
A spring insertion hole 442 communicating with the coil spring 44 is bored in the spring insertion hole 442.
An actuating plate 446 that is biased upward by the actuating plate 446 is arranged so as to be prevented from coming off. The actuating plate 446
A recess 446a is provided on the upper side of the
The tip of the leaf spring contact piece 444 extends above the bottom 446b of the recess 446a. That is, when the operating knob (not shown) is not pressed, the operating plate 446 is pressed as shown in FIG.
The tip of the leaf spring contact piece 444 is elastically displaced upward to connect the fixed contact 443 and the movable contact 444a.
It is kept in the OFF state. Operation knob (not shown)
When pressed, the operating rod 316 having a flat lower surface presses the upper end of the operating plate 446 in the direction of the pole plate 4. Then, the elastic deformation of the leaf spring contact piece 444 is released, and the fixed contact 443 and the movable contact 444a are
When turned on, the second switch section 44 is activated.

[Effects of this invention]

As described in detail above, the compound switch of the present invention has an operation knob that can be operated in two modes: rocking operation and pressing operation, so that the two switch parts can be switched with a single operation knob. This eliminates the need for the operator to select an operating knob, resulting in improved operability.

Furthermore, compared to the prior art, the composite switch of the present invention has a reduced number of parts and a simplified structure, so it is easy to assemble, and in addition, it can be made smaller and lower in cost.

Furthermore, since the operating knob is swingably supported on the inner case that moves up and down, the single operating knob can be operated in two different ways: horizontal swinging operation and pressing operation.
The two operating modes can be separated and transmitted to different corresponding switch sections. Moreover, since each switch portion is structured as a sliding switch mechanism in which each movable contact piece is independent of the other and slides on a single pole plate, a stable switch action can be obtained.

Furthermore, since the two switch sections are arranged together, assembly is easy and connection with external wiring is facilitated.
