Abstract

Interrupteur manométrique commandé par un piston ou membrane contre l'action d'un ressort de rappel avec point d'interruption réglable L'interrupteur est caractérisé en ce que le piston 32 ou la membrane se trouve en liaison active avec un levier d'interrupteur 28 monté à pivotement, qui actionne l'organe de commutation 12, 11 et qui, par l'intermédiaire d'un contre-appui 27 déplaçable dans la direction longitudinale du levier d'interrupteur 28 est soumis à l'action d'un ressort-lame en sens contraire au couple exercé par le piston 32 ou la membrane. Application aux interrupteurs manométriques.
