Abstract

A steering column switch for motor vehicles comprises a base plate and first, second, and third identical microswitches placed onto the plate that are indirectly actuated by an operating lever through terminal links. The operating lever has a neutral position and two operating positions. The third microswitch that is assigned to the neutral position is arranged in a flat position. The terminal link actuating the third microswitch is arranged in a plane parallel to the base plate. A sampling roller prevents frictional losses during the actuation of the third microswitch via a control contour on the control lever.
