Abstract

L'invention concerne un dispositif commutateur à verrouillage électronique pour un circuit électrique. Le dispositif, subordonnant la commutation du circuit à l'actionnement successif, dans un ordre déterminé constituant un code, d'au moins N moyens d'excitation correspondant respectivement à N bornes d'entrée du dispositif, où N est au moins égal à trois, est caractérisé en ce qu'il comporte un circuit de premier rang comportant une première borne reliée à une entrée d'un circuit ET auto-maintenu, N-1 circuits de n-ième rang où n varie de deux à N inclus, comportant une n-ième borne, un n-1-ième circuit OU auto-maintenu, un n-1-ième inverseur et un n-1-ième circuit ET NON, N moyens d'excitation des bornes par mise à la masse, des moyens pour établir une liaison entre chaque moyen d'excitation et une borne pour établir le code, et des moyens de comparaison entre les signaux de sortie respectifs des N circuits.
