Patent

CA 2041375

A display device with a movable element drives the movable element between ON and OFF positions by means of switching the polarity of a first high remanence magnetic core. A reed switch located in the return flux path of the magnetic core and of a second core so that in one and the other polarity of the first core the reed switch assumes open and closed states.

Cette invention concerne un dispositif d'affichage à élément mobile qui déplace cet élément entre une position ON et une position OFF par inversion de la polarité d'un premier noyau magnétique à haute rémanence. Un commutateur à lame souple est situé sur le trajet du flux de retour dudit noyau magnétique et d'un second noyau de façon que, selon la polarité du premier noyau, il passe à l'état ouvert ou fermé.
