Abstract
A steering column switch has two switching members superposed in a housing, which are swivellable about two parallel axes at least substantially diametrically opposite each other relative to a central aperture and tiltable perpendicularly to the swivelling plane. Two planar insulating plates provided with metal conductors stand perpendicularly on the swivelling plane. Each insulating plate has a free end formed as plug part and on one of these plates it is changed over when one switching member is tilted. To simplify the construction of the switch and to lower contact resistances switch contacts are also changed over on one of the two perpendicularly standing insulating plates with a tilting of the other switching member and with a swivelling of each of the two switching members.
