Abstract

Commutateur du type << poussé-poussé >> ou l'exécution des commutations commandées est subordonnée à l'apparition d'une impulsion d'une suite d'impulsions récurrentes appliquée à un circuit auxiliaire, ce commutateur présentant un minimum de parties mécaniques. L'enfoncement d'une touche principale telle que 10 provoque la fermeture de l'interrupteur 11, conditionnant le circuit auxiliaire 40 de manière qu'il fournisse une impulsion pour la première impulsion de la suite qui lui est appliquée en 45, puis celle de l'interrupteur 12 modifiant le signal apparaissant en D sur le basculeur de type D, 17. L'impulsion fournie par le circuit 40 appliquée à l'entrée d'horloge du basculeur 17 et des autres basculeurs modifie l'état du seul basculeur 17. La touche 30 est une touche de rappel à zéro. Application aux commutateurs sur des circuits parcourus par des signaux de télévision.
