Abstract

a. Commutateur de commande de vitesse de précision. b. Commutateur facilement transformable pour travailler comme commutateur normalement ouvert en un commutateur normalement fermé et inversement, par le simple changement de deux branchements du circuit, avec une plage étendue de vitesses de fonctionnement qui puisse se régler facilement pour divers retards de mise hors service, le retard de mise hors service étant l'intervalle de temps entre la décélération de l'arbre d'entrée en dessous d'une vitesse critique et l'inversion du commutateur vers l'état de fonctionnement d'origine.
