Abstract (en)
[origin: WO8604440A1] An electromagnetic indicator device which has a plurality of triangle-shaped trip-flaps (7), asymmetrical in relation to the rotation axis, which are arranged on a board (1) in the form of a matrix. A polarization magnet is applied to the trip-flap in the vicinity of the rotation axis. The movement of the rotatably supported trip-flaps from a first position into a second position is effected, as appropriate, by a permanently associated electromagnet (19) fixed behind the board (1). A network of support blocks (2) is fixed to the board (1), whereby each four support blocks (2) form the corner points of a square.
