Abstract
The present invention concerns a switch, preferably a steering column switch for an automobile, with which both control currents and load currents are to be controlled. The object of the present invention is to mostly prevent soil and scale from forming on the contact surfaces. The present invention achieves this object by transforming the grinding movement of the operating element into a movement of the contact points perpendicular to one another with the help of a mechanical control. Advantageous embodiments involve the design and positioning of the contact points as well as the design of the mechanical control and a method of assembling the switch according to the present invention.
