Abstract

Selon un mode de réalisation, l'interrupteur comprend une membrane souple non métallique installée de façon étanche à l'intérieur dudit logement et appliquée contre la face de ce disque qui est la plus éloignée dudit siège, cette membrane divisant cette cavité en deux chambres, à savoir une chambre sous pression communiquant avec ladite ouverture de passage de fluide et une chambre pour disque isolée de la première chambre, de telle manière que les forces qui prennent naissance dans ladite chambre sous pression soient appliquées par ladite membrane pour faire passer ce disque de l'une à l'autre de ces positions stables.
