Abstract

L'invention concerne un procédé permettant de faire fonctionner un appareil de commutation comprenant au moins un dispositif de commande électromagnétique (1) présentant une armature mobile (10) pour l'ouverture et la fermeture d'au moins un contact principal (15) de l'appareil de commutation. L'invention est caractérisée en ce qu'on détecte une variation de flux magnétique dans le dispositif de commande électromagnétique (1), entre une première position (arrêt) lorsque le contact principal (15) est hors circuit, et une seconde position (marche) lorsque le contact principal est en circuit, et en ce qu'un courant de bobine (i) du dispositif électromagnétique (1) est limité à une valeur minimale prédéterminée (IL) dans la seconde position ( marche), si la variation de flux magnétique dépasse une valeur prédéterminée. Ceci est particulièrement avantageux, du fait qu'un mouvement d'actionnement de l'armature (10) peut être détecté de façon sûre, même si une variation correspondante du flux magnétique est mesurée. La saisie métrologique du flux magnétique s'effectue en outre sans contact.
