ABSTRACT:
An indicator device for an indicator formed of individual indicator elements, having an optical fiber with a corresponding bore in an indicator board located in front of the indicator elements for each indicator element. Switching elements are disposed between the ends of the optical fibers and the corresponding bores of the indicator board, each said switching element corresponding to an individual optical fiber. The switching elements are selectively brought into a non-indicating position by electromagnets, where they cover the end of the assigned optical fibers, or into an indicating position, where the optical fiber is uncovered. This indicator device is utilized for displaying arbitrary luminous signals whereby each optical fiber is closed off by a reflecting body which extends into an indicator board and which is held in a hole in the bottom of the indicator compartment.
