Signal display element for the display of more, than two informations for signal displays with electro-magnetically excited magnetic tilting plates

A signal display element for displaying more than two informations comprising electromagnetically excitable magnetic tilting plates, a base plate, said tilting plates being supported in bearings on the base plate for rotation about an axis of rotation, said tilting plates containing parts including magnets being offset with respect to magnets of an adjacent plate in the direction of the axis of rotation, wherein the magnetic axes of the magnets run substantially normal to the plane of the associated tilting plate, bipolarly excitable field coils coupled to the tilting plates for the rotational control thereof, the parts of the tilting plates containing the magnets are thicker than the non-magnetic parts of the tilting plates, the distance between the outer surfaces of the two outermost lying tilting plates when the tilting plates are stacked and laid on each other on one side of the axis of rotation is equal to the total thickness of the non-magnetic parts of the tilting plates less by one than the number of all the tilting plates, and of the thickness of a magnet having maximal thickness and arranged on a tilting plate taken together with that tilting plate.
