Abstract
Viene previsto un pressostato di sicurezza particolarmente per microinterruttori comprendente un corpo di base impegnabile ad un recipiente contenente un fluido in pressione, una membrana flessibile disposta a contatto del fluido in pressione ed operante su un microinterruttore connesso allo stesso pressostato, una calotta di protezione atta ad alloggiare la membrana flessibile, e mezzi di attivazione atti a trasmettere la spinta della membrana allo stesso microinterruttore attraverso la calotta di protezione
