  • Patent number: 4139749
    Abstract: A switch actuated by a control lever associated with a steering column for operating direction-indicating lamps, switching the headlights to low and high beam, operating the screen wiper and actuating similar functions includes a housing in which an end portion of a flexible band-type cable is fixed. The control lever is mounted in the housing for rocking about a pair of mutually perpendicular axes and actuating a pair of sliders each guided within the housing for movement along one of the axes. The band-type cable includes a plurality of printed conductors covered by an insulation. At the end portion of the cable, the conductors have exposed portions not covered by the insulation, which exposed portions form fixed contacts cooperating with movable contacts carried by the sliders. The remaining portion of the cable extends outwardly of the housing for connecting the fixed contacts to a power supply and the respective electrical devices operated by the switch.
