Abstract: A multi-way change-over switch which is compact with a reduced number of parts and is improved in operability. The multi-way change-over switch comprises a manually operable lever, a rotary slider supporting the manually operable lever for rocking motion thereon and connected for integral rotation by rotation of the manually operable lever, a rotary switch mechanism having a plurality of contacts which are changed over by rotation of the rotary slider, a slide switch mechanism connected to be slidably moved in a linear direction to change over a plurality of contacts thereof by rocking motion of the manually operable lever, and a controlling mechanism for controlling a direction of sliding movement of a slider of the slide switch mechanism. The manually operable lever can be tilted and rotated to operate the slide switch mechanism and the rotary switch mechanism, respectively, to achieve various switching operations.

Abstract: A power seat switch device for adjusting a seat position having a single operating knob, a sliding member cooperatively connected to the operating knob, and three lever switches adapted to be selectively operated by the motion of the sliding member. When the common operating knob is moved in one of two opposite directions, the first switch is operated to move the seat to the front and to the rear. On the other hand, when the operating knob is rotated at one end, the sliding member is pivoted about the third switch, thereby operating the second switch. As a result, the height of the front portion of the seat is adjusted. In contrast, when the operating knob is rotated at its other end, the sliding member is pivoted about the second switch, thereby operating the third switch. As a result, the height of the rear portion of the seat is adjusted.
