Abstract: Signal display element for the display of more than two informations by electromagnetically excited magnetic tilting plates, wherein at least two tilting plates in stable condition are arranged and supported in bearings on a baseplate for covering the surfaces of the baseplate carrying the information, the single tilting plates are supported in bearings preferably on two places and displaced in relation to each other, the distance between the common geometric axis of revolution of the tilting plates and the baseplate equals to, or is larger than the half of the total thickness of the tilting plates bearing up against one another.

Abstract: A signal display element for the display of more than two informations with electromagnetically excited magnetic tilting plates supported in bearings on a baseplate (1 ) and displaced axially in relation to one another, provided with at least one magnetic part each, and the magnetic axes of the magnetic parts (4) are normal to the plane of the tilting plates (3), bipolarly excitable electromagnets are provided for controlling the radiation of the tilting plates (3) about the axis of rotation and on the ends of electromagnetic cores (5) facing the baseplate (1) guide plates (6) are axially displaced, the number of the tilting plates (3) is larger at least by one, than the number of the guide plates (6), but their number is less at least by one, than the power of two with an exponent corresponding to the number of cores (5).

Abstract: A signal display element for the display of more than two informations by electromagnetically excited tilting plates supported in bearings on a baseplate (1) and containing magnetic parts and adapted to be rotated about an axis of rotation (3), wherein the magnetic axes of the parts of the tilting plates containing the magnets (5) run normal to the plane of the tilting plate, bipolarly excitable field coils are coupled to the tilting plate (4) for controlling the rotation thereof.
