Abstract

Commutateur électrique de type rouleau comprenant au moins une électrode mobile et une électrode fixe dont la surface comporte des conducteurs et la partie médiane possède une plaque isolante. L'électrode mobile est reliée au système de commande et peut rouler sur l'électrode fixe afin de coupler les conducteurs quand elle est mue par le système de commande. Les conducteurs présentent des tolérances diverses. Ce commutateur électrique fonctionne au moyen de l'effet d'amplification du signal de force produit par la friction de roulement et peut servir dans des relais de véhicule automobile, des relais haute puissance ou sous forme de commutateur électrique, contact ou coupe-circuit de courant alternatif.
