Abstract

Dans la présente invention, une première partie d'ouverture/fermeture mobile est disposée de manière à être séparée d'un premier contact mobile dans la direction longitudinale d'une pièce de contact mobile. Une seconde partie d'ouverture/fermeture mobile est disposée de façon à être séparée d'un second contact mobile dans la direction longitudinale. Lorsque la pièce de contact mobile se déplace dans une direction de contact : la première partie d'ouverture/fermeture mobile et une première partie d'ouverture/fermeture fixe viennent en contact mutuel avant que le premier contact mobile et un premier contact fixe n'entrent en contact ; et la seconde partie d'ouverture/fermeture mobile et une seconde partie d'ouverture/fermeture fixe viennent en contact mutuel avant que le second contact mobile et un second contact fixe n'entrent en contact.
