Automatically resettable trafficator control

摘要

The control comprises a single roller (34) acting on a cylindrical section of the steering column (27) which causes automatic resetting of the trafficator control when the column (27) is rotated in the opposite direction. The roller (34) is coupled to a cam shaft (21) via a cam (20). A further cam (19) attached to the cam shaft (21) operates electrical contacts via respective switch heads (24a,24b). The second cam (19) is coupled to the trafficator operating control (1) via a rotary lever (14), so that rotation of the cam shaft (21) is used to return the operating control (1) to the off position.
