Abstract

L'invention concerne la commutation à l'état conducteur des dispositifs de commutation à champs croisés. Elle se rapporte à un dispositif muni d'une anode et d'une cathode entre lesquelles un gaz à faible pression est disposé, un dispositif 18 appliquant un champ magnétique principal à l'espace séparant les électrodes. Selon l'invention, une bobine 32 applique un champ magnétique auxiliaire qui provoque, dans une petite partie de l'espace séparant les electrodes, une décharge luminescente qui suffit à l'amorçage de la commutation. Application aux dispositifs de commutation à champs croises.
