Abstract

L'invention concerne un interrupteur limiteur de niveau commandé par flotteur. Interrupteur caractérisé en ce que l'équilibrage de poids est assuré par la force d'attraction magnétique permanente entre des éléments de champ magnétique 12, 13, 14 dont l'un est fixé au tube, au-dessus de la butée supérieure 9, et un autre est fixé au flotteur 6, et dont au moins un est doué de magnétisme permanent L'invention est plus particulièrement applicable dans le domaine du contrôle de niveau de liquides.
