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