Description

  The present invention mainly relates to a multidirectional operation switch structure used for vehicles such as automobiles, and more particularly to a multidirectional operation switch structure with improved operational feeling.

  Conventionally, a multidirectional operation switch structure as shown in FIGS. 11 and 12 is known (see, for example, Patent Document 1).

  First, in terms of configuration, in this conventional multidirectional operation switch structure, a pin member 3 is erected at the center of the lower case 1 via a return spring member 2 and formed on the pin member 3. The substantially spherical upper end portion is elastically brought into contact with the lower surface side of the concave portion 4 a of the sliding case 4.

  The sliding case 4 is supported in a swingable manner together with a dial operation portion 6 that protrudes upward from the upper case 5.

  Then, the lever switches 8 and 9 fixed to the back side 7a of the wiring board 7 interposed between the dial operation unit 6 and the sliding case 4 are operated by operating the dial operation unit 6. As shown in FIG. 12, the operating levers 8a and 9a that are projected are tilted downward from the lever switches 8 and 9 by the two slide plates 10 and 11 that are arranged orthogonally. Thus, the on and off switch operations can be performed.

  The multi-directional operation switch structure is provided with a fixed contact 12 and a movable contact 13 that change the connection position by the rotation operation of the dial operation unit 6, and on and by the pressing operation of the push button 15. Push switches 14 that can be turned off are fixed to the upper surface side 7b of the wiring board 7, respectively.

  Next, the operation of this conventional multidirectional operation switch structure will be described.

  In this conventional multi-directional operation switch structure, as shown by the two-dot chain line in FIG. 12, when the dial operation unit 6 is moved in the direction of the white arrow, the lever switches 8 and 9 are connected to the wiring board 7. At the same time, it is slid and engaged with two orthogonally arranged slide plates 10 and 11, so that the operation levers 8 a and 9 a that protrude from the lever switches 8 and 9 tilt downward. Then, on and off switch operations are performed.

Depending on the tilt direction of these operation levers 8a and 9a, different types of on and off switches are switched in the eight directions.
