SIGNAL DISPLAY ELEMENT FOR THE DISPLAY OF MORE, THAN TWO INFORMATIONS FOR SIGNAL DISPLAYS WITH ELECTROMAGNETICALLY EXCITED MAGNETIC TILTING PLATES

摘要

A signal display element is used for the display of more than two pieces of information on a signal display having electromagnetically excited magnetic tilting plates. The element has at least two tilting plates arranged in stable condition and supported in bearings on a baseplate, being suitable for covering the surfaces of the baseplate carrying the pieces of information. The invention is characterized in that the tilting plates are supported in bearings preferably at two places and are displaced in relation to each other. The distance between a common geometric axis of revolution of the tilting plates and the baseplate is equal to or larger than half the total thickness of the tilting plates that bear against one another.
