Abstract

Les contacteurs-interrupteurs ou les relais, en particulier, sont habituellement pourvus d'un système d'électro-aimant comprenant une bobine avec une armature et une culasse. Il a déja été proposé un dispositif servant à la régulation dépendante du temps du flux magnétique dans le système d'électro-aimant, selon une courbe nominale calculée avec précision pour chaque modèle d'électro-aimant. Selon l'invention, le dispositif de régulation (10) régule le flux magnétique dans une plage prédéterminée qui est indépendante du temps et de la course. De préférence, le dispositif de régulation (10) régule le flux magnétique au moyen de la bobine (1, 21) (flux de bobine). En particulier la plage étroite réglée pour le flux de bobine peut être indépendante du temps et de la course, ce qui était impossible selon l'état antérieur de la technique.
