Abstract

Dispositif de commutation comportant au moins un contact fixe et un bras supportant un contact mobile et monté sur un porte-contacts pouvant prendre des première et seconde positions, ledit bras pouvant se déplacer entre des troisième et quatrième positions lorsque le porte-contacts se trouve dans la première position Un organe de verrouillage 701 coopère avec une surface de verrouillage 702 pour empocher le bras 31 de rebondir vers la troisième position après qu'il ait effectué un mouvement prédéterminé en direction de quatrième position sous l'action de forces électrodynamiques, des moyens 731 étant prévus pour défaire le verrouillage lorsque le porte-contacts 90 passe de la seconde dans la première position. Application démarreur de moteur.
