Abstract (en)
[origin: US4733231A] A system for displaying a segment as applicable in particular to remote-controlled digital display. A control circuit energizes two stationary series-connected electromagnets with pulses of the same polarity so as to produce a magnetic field in each electromagnet. Under the action of the magnetic field, a single permanent magnet rigidly fixed to the segment is capable of displacement between the electromagnets in order to move the segment from a visible active position to a hidden active position.
