Abstract: front page image
(EN)A switching device comprising at least two operating coils (21, 22, 41, 42) for controlling at least two magnetic circuits (51, 52), a control unit (35) which controls the voltage supplied to the operating coils, and individual demagnetization circuits (31, 32) connected to each operating coil for achieving a simultaneous opening of the at least two magnetic circuits from all the operating coils.
(FR)La présente invention concerne un dispositif de commutation comportant au moins deux bobines de commande (21, 22, 41, 42) permettant de contrôler au moins deux circuits magnétiques (51, 52), une unité de commande (35) qui contrôle la tension fournie aux bobines de commande, et des circuits individuels de démagnétisation (31, 32) reliés à chaque bobine de commande permettant d'effectuer une ouverture simultanée desdits au moins deux circuits magnétiques à partir de toutes les bobines de commande.
