Description

[Detailed Description of the Invention] The present invention relates to a switch device used for power windows of automobiles, etc.

Traditionally, switch devices used for automobile power windows, for example, have a manual function that opens and closes the window only while the operator is operating it, and stops opening and closing as soon as the operator releases the operator's hand. Some devices have an automatic function that allows the window to open and close completely even if you release the control once you operate the control. In order to keep it simple, the contacts for the manual function are closed and utilized as part of the automatic function operation. For this reason, in the past, one operator was made to be able to operate in two stages by swinging or sliding, and the first stage operation closed the contact for the manual function, and the second stage In addition to the contacts for the manual function, the contacts for the automatic function are closed by operation. However, with this device, there is a problem of erroneous operation where the force exceeds the force when operating the first stage and operates the second stage. and a second operator, and the second operator is incorporated in the center of the first operator, and the contact for the manual function is created by swinging the first operator. There is also a device in which the contact for the automatic function is closed in addition to the contact for the manual function by swinging the second operator. However, since the operating modes of the two controls are the same in terms of swing as described above, when you think you are operating the first control, you are actually operating the second control. There was still a problem with incorrect operation.

The present invention has been devised to solve the above-mentioned problems, and therefore, its purpose is to provide a switch device that can perform two different functions with a clear difference and can be operated accurately. be.

An embodiment of the present invention will be described below with reference to the drawings. First, in FIGS. 1 and 2, 1 is a base, 2 is a cover, and the center of the base 1 is shown in FIG. 3. On both sides of the protruding moderation peaks 3, movable contact plates 4 and 5 made of leaf springs as shown in FIG. The parts are fastened together with power supply terminals 6, 6 arranged on the back side of the base 1 by rivets 7, 7, respectively. On the other hand, fixed contacts 8, 9, 10, which correspond to the ends of the movable contact plates 4, 5, which are the movable contact parts, are provided on the upper and lower parts of the base 1, respectively.

In this case, both ends of the first operating element 18 are brought into contact with the protrusions 13 that receive the elastic force of the spring 14, as shown in FIG. Both the upper and lower parts normally protrude uniformly from the opening 20 that exists. Further, this first operator 18 has pressing parts 21, 21 as operating parts as shown in FIG. 4 at both ends of the portion located on the movable contact plate 4, respectively.
is installed protrudingly. Further, 22 is a second operator incorporated in the center of the first operator 18, and in detail, a pressing part 23 as an operator as shown in FIGS. 3 and 4 is provided on the back side. 23 as well as claws 24, 24 as shown in FIG. 5 elastically engaged with the rail portions 26, 26 provided on the sides;
It is provided so that it can be slid up and down along the rail portions 26, 26, and by subsequently attaching the first operator 18 as described above, the second operator 22 can be moved up and down. It is provided in the center of the first operator 18 so as to partially protrude from the opening 27 existing in the center of the first operator 18 . In addition, in the attached state, the pressing portion 2 of the second operator 22
3 and 23 face both of the movable contact plates 4 and 5. Incidentally, 28 is a spring 3 which corresponds to the above-mentioned moderation thread 3 in the center hole 29 of the second operator 22.
It is a moderation ball that is stored together with 0.

Therefore, in the case of this embodiment configured as above,
Now, when the first operator 18 is swung by pressing the upper or lower part of the first operator 18, the upper or lower part of the movable contact plate 4 is pushed by either of the pressing parts 21, 21. In other words, when the upper part of the first operator 18 is pressed, the movable contact plate 4
When the upper part of the movable contact plate 4 is pushed in, and conversely, the lower part of the first operator 18 is pressed, the lower part of the movable contact plate 4 is also pushed in. The movable contact plate 4 with the upper part pushed in contacts the fixed contact 8 to close the gap between the power supply terminal 6 and the fixed contact 8, while the movable contact plate 4 with the lower part pushed in contacts the fixed contact 8. 9 to close between the power supply terminal 6 and its fixed contact 9. Also, at this time, with the swinging operation of the first operator 18 mentioned above, the protrusion 1
3 are each pushed in against the elastic force of the spring 14, and when the operation is released, the spring 14 releases its elastic force, so that the first operator 18 is immediately activated using the spring 14 as a return means. will be reinstated.
On the other hand, when the second operator 22 is slid up and down, either the upper part or the lower part of the movable contact plates 4 and 5 is pushed by either one of the pressing parts 23, 23. That is, when the second operator 22 is slid upward, the upper portions of both movable contact plates 4 and 5 are pushed in, and conversely, when the second operator 22 is slid downward, the movable contact plates 4 and 5 are pushed in. 5 as well, both lower portions are pushed in. The movable contact plate 4 is as described above, and in addition, the movable contact plate 5 is
