ABSTRACT:
A magnetically operated display element comprises a disc of substantially non-magnetic material, provided on opposite sides with ears extending transversely in the same direction relative to the disc, said ears being designed to allow the pivotal mounting of said disc on supporting means. The disc is contrastingly colored on opposite surfaces and shaped so that concavities are provided as viewed on one of said surfaces, such concavities being on opposite sides of and defining on the surface on which they appear a ridge extending across said disc approximately parallel to the pivotal axis of the disc; the concavities and ridge appearing on the opposite surface as convexities and a valley.
