<p>The switching unit (1) has the switching member (3) on the front side and the switching member (4) on the back side which are mutually mechanically and electrically connected when mounted on the spoke portion (2) of the steering wheel, and is designed such that when the switching members (3,4) are assembled in one unit (1), the elastic electrode portion (6) on one side comes into elastic contact with the electrode pattern portion (5) on the other side. The switching members (3,4), therefore, are not required to be assembled into one unit prior to installation to the steering wheel, being little restricted in shape and size. In addition it is possible to dispense with such a complicated operation as electrically connecting the switching members (3,4) by a wiring harness after installation to the steering wheel, therefore improving the ease of installation. Furthermore, since there is no necessity to form a through hole in the spoke portion (2) of the steering wheel, the steering wheel will not be deteriorated in mechanical strength. <IMAGE></p> |
