: The invention relates to a signal display element for the display of more, than two informations for signal display with electromagnetically excited tilting plates, having baseplate, tilting plates supported in bearings on the baseplate and containing parts with magnets, having been displaced in relation to each other in direction of the axis of rotation, wherein the magnetic axes of the parts of the tilting plates containing the magnets run advantageously normal to the plane of the tilting plate, further on bipolarly excitable field coils are ordered directly or indirectly to the tilting plate, being well suitable for the control thereof. The essence of the invention is that the parts of the tilting plates containing the magnets are thicker, than the non-magnetic parts of the tilting plates, further on, the distance between the outer surfaces of the two (extreme) tilting plates, when the tilting plates are accumulated and laid on each other on one side of the axis of rotation, being equal to the total thickness of the tilting plates, corresponds to the sum of the (total) thickness of the non-magnetic parts of the tilting plates, the number of which is less by one, than the number of all the tilting plates, and of the thickness of the magnet of maximal thickness having been arranged on the tilting plate. |
