Abstract

a. Dispositif pour la production de signaux de sortie pouvant se modifier en fonction de la vitesse de rotation. b. Dispositif caractérisé en ce qu'il est prévu des moyens pour fixer au moins deux valeurs de seuil pour la tension d'émission comme niveau de fermeture, ainsi qu'une valeur de seuil comme niveau d'ouverture, pour les signaux de sortie, et en ce que l'on peut déclencher, sous l'action de la vitesse de rotation du dispositif émetteur, une commutation faisant passer de l'un à l'autre des niveaux de fermeture, qui sont au moins deux. c. L'invention s'applique notamment aux moteurs d'automobiles.
