Abstract

A relay arrangement for transmitting electrical signals from various switches of an automobile to various devices controlled by the switches comprises a cable, and a boss plate rotatably held to the steering shaft of the automobile. The cable has a spiral winding between two sun gears, and the boss plate extends between two neighboring turns of the winding. The number of turns of the winding is in excess of the maximum number of revolutions that the steering wheel can make. When the boss plate is rotated during the rotation of the steering wheel, the plate slides through the winding in a plane perpendicular to the axis of the winding.
