Abstract

L'invention concerne un relais sans contacts. Dans ce relais, qui comporte un pont redresseur sur deux alternances 4 à 7, un triac 3, une charge 22, un thyristor 8 relié au pont et deux transistors 9, 16, il est prévu un amplificateur de courant 14 relié à une borne 12 d'un courant continu et par une diode Zener 10 à la borne de commande du transistor 9, tandis que sa sortie est reliée à la borne 12 et à l'entrée de commande du thyristor 8 par l'intermédiaire de la voie de charge du transistor 16. Application notamment aux relais purement électroniques.
