Signal display element for the display of more, than two informations for signal displays with electromagnetically excited tilting plates

Signal display element for the display of more than two informations comprising electromagnetically excited magnetic tilting plates, a baseplate, said tilting plates being supported for rotation about an axis in bearings on the baseplate and displaced around the axis in relation to one another, said tilting plates each including at least one magnetic part, the magnetic axes of the magnetic parts are normal to the plane of the tilting plates, bipolarly excitable electromagnets each coupled electromagnetically to an associated one of said magnetic parts for controlling the tilting plates, on the ends of electromagnetic cores of said electromagnets facing said baseplate, guideplates preferably parallel with the baseplate are arranged, the guideplates each being associated with one tilting plate are axially displaced, the number of the tilting plates is larger at least by one than the number of the guide plates, the number of the tilting plates which can be energized is defined by the following relationship:

• Number of tilting plates=2.sup.n -1;
• wherein n is the number of the electromagnetic cores, and wherein the electromagnetic cores are made of a hard magnetic material with reversible polarity and remanent magnetic induction, and wherein at least a part of the cores is shunted with a coupling member to be fitted closely to the cores, said coupling member being formed of a soft magnetic material, ensuring magnetic distribution, at the ends of the cores lying opposite to the baseplate.
