【Example】

 A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The present invention will be described with respect to the configuration of a vehicle wiper / washer switch device as an example of a lever switch, but the invention is not limited to this embodiment. 2 is fitted. A support shaft 3a is pivotally mounted between the case 1 and the base 2 so that the actuation plate 3 can be swung left and right about the first axis V. A support shaft 4a is pivotally mounted in the operation panel 3 for vertically swinging the operation lever 4 about a second axis W that is substantially orthogonal to the first axis V.

The operation lever 4 penetrates the operation board 3 and has a bottomed hole 4 b opened in the extending direction at the tip thereof. A pressing pin 6 urged by a compression spring 5 is inserted into the hole 4b and engaged with a moderation ridge 1a formed on the inner wall surface of the case 1 to prevent the operation lever 4 from swinging up, down, left and right. To form a moderation mechanism that gives a sense of moderation.

The case 1 contains a wiper switch 7 as a first switch and a washer switch 8 as a second switch. The wiper switch 7 includes a movable contact 7a fitted on the lower surface of the operation board 3 and a plurality of fixed contacts arranged on the upper surface of the base plate 2 in a substantially arc shape centered on the first axis V as shown in FIG. This is a form of a so-called sliding switch that is configured by the contact 7b.

The washer switch 8 is composed of a movable contact piece 9 extending in the extension direction of the operating lever 4 and a pair of fixed contacts 10 and 11 facing the pair of contact portions 9 d and 9 e of the movable contact piece 9. . As shown in FIG. 3, the pair of fixed contacts 10 and 11 are arranged on the upper surface of the base 2 in an arc shape of two rows centered on the first axis V. The movable contact piece 9 is a wire material having conductivity and elasticity, and the base end 9a is formed in a substantially U shape as shown in FIG. 6, and the arms 9b and 9c extending from the base end 9a are formed at a substantially right angle. It is bent so as to be parallel to each other. Contact points 9d or 9e are formed near the tips of the arms 9b and 9c, respectively. The movable contact piece 9 is not limited to the wire member, but may be a leaf spring member as shown in FIG. 7, for example.

As shown in FIGS. 4 and 5, the operation lever 4 has a groove portion 4c in which a movable contact piece 9 is disposed on the lower surface, and a through hole 4d is formed between the vicinity of the bottom of the hole 4b and the groove portion 4c. I am in touch with. Further, a projection 4e is provided on the bottom of the hole 4b. Then, the movable contact piece 9 is attached to the operation lever 4 by inserting the base end 9a from the through hole 4d and hooking it on the protrusion 4e. As shown in FIG. 4, this movable contact piece 9 has its base end 9a pressed by the compression spring 5 when the pressing pin 6 urged by the compression spring 5 is engaged with the moderation crest 1a. It does not fall off from the operating lever 4. The structure for mounting the movable contact piece 9 on the operation lever 4 is not limited to the above-mentioned embodiment, but may be a structure in which the movable contact piece 9 and the movable contact piece 9 are coupled to each other by snap fitting, fixing, or the like. The convex portion provided on the movable contact piece 9 may be fitted into the concave portion formed in FIG.

Each arm 9b and 9c of the movable contact piece 9 is supported near the base end 9a by a step 4f formed in the groove 4c, and this position is a reference point for elastically deforming inward of the groove 4c. Becomes Further, the operating lever 4 restricts the hanging down of the arms 9b and 9c by a restricting portion 4g extending from the bottom surface toward the groove 4c. As a result, an appropriate contact gap between the contact portions 9d and 9e and the fixed contacts 10 and 11 is secured. In the movable contact piece 9, the first contact portion 9d is in contact with the first fixed contact 10 and the second contact portion 9e is in contact with the second fixed contact 11 so as to be in contact with each other.

Next, the operation of the lever switch having the above structure will be described. When the operation lever 4 is swung in the left direction L or the right direction R shown in FIG. 2, the actuation plate 3 swings in the same direction and switches the movable contact 7a to the conduction with the corresponding fixed contact 7b. Then, the wiper switch 7 stops the wiper driving motor (not shown) and switches the rotation speed. The operating lever 4 is normally in the neutral position N shown in FIG. 4, and the washer switch 8 is in the off state.

Next, when the operation lever 4 is swung upwards, the contact portions 9d and 9e of the movable contact piece 9 come into contact with the fixed contacts 10 and 11 and become conductive. After that, when the operating force of the operating lever 4 is released, the operating lever 4 automatically returns to the neutral position N by the moderating action of the pressing pin 6 and the moderating ridge 1a, and the contact portions 9d and 9e are fixed to the fixed contact 10 and the fixed contact 10 respectively. It is separated from 11. Then, the washer switch 8 switches between rotation and stop of a washer motor (not shown).
