<p>The indicator device's elements (1), can be actuated by an electromagnetic device to form digits and characters. Each indicator element is rotatable so that it can assume two different positions, one active and one inactive. The device has a core (5) surrounded by a coil (4) and has one or more permanent magnets (6, 7). The indicator element is attached to a tuning member (2) enclosing the coil. The pivot of this member is at right angles to the longitudinal axis of the core and symmetrical between the two core ends.</p> |
