Abstract

Abstract Switches are disclosed for controlling turn signal and hazard warning lights in automotive vehicles. The switches are concentrated in a small space in the steering column. Use is made of movable contact carriers in association with rotatable ball and leaf spring contacts to enable establishment of a number of different circuits. Elements are provided to enable lane change indications to be signalled without latching the switch and permitting cancellation of the lane change signal simply by release of the turn signal lever. Automatic return to neutral is provided for latched turn indications. A separate hazard warning control enables hazard warning signals through common switching elements regardless of the condition of the turn signal circuits.
