Abstract
A steering column switch for motor vehicles comprises at least one wiper/washer switch ( and ), which is an integral part of a switch lever ( ), whereby the contact bridge ( and ) of the wiper/washer switch is held in position on a rotary switch member ( and ) and acts with several contact arms ( ) on switch contact paths ( and ) with associate connection contacts ( and ). The contact bridge ( and ) and the switch contact paths ( and ) interact to transfer switch function data in Gray code. This type of coding permits a reduced number of connection lines ( ) and connection contacts ( and ), compared with the number of switch positions and, at the same time, permits relatively high switching reliability.
