Abstract

E' rappresentato un pressostato o interruttore a pressione il quale è alloggiato in un contenitore sotto pressione (1) riempito con un gas ad una prima pressione (P1), per esempio un cuscino d'aria di sicurezza in un autoveicolo. Il dispositivo comprende un contenitore a pressione (12) riempito con un gas ad una seconda pressione (P2), il quale contenitore ha su un lato un diaframma flessibile (18) che reagisce alla differenza delle due pressioni ed interagisce con un circuito elettrico. Il contenitore è fornito con un lato adiacente ed opposto ad una porzione di parete (14, 106, 214, 238, 256) del recipiente a pressione ed un elemento magnetico (16, 26, 240, 246/248) è operativamente collegato al diaframma. La porzione di parete del recipiente a pressione è realizzata con materiale non magnetico ed in prossimità dell'altro lato della porzione di parete è montato un elemento di commutazione (40), sensibile al campo magnetico, in opposizione all'elemento magnetico a diaframma. Un'armatura (232, 254) che si estende attraverso la por
