Abstract (en)

A pressure switch includes a container (1) closed by a cover (4) and inside which there is arranged a membrane (2), as well as a microswitch (5) mounted on the cover (4) so as to be activated upon rising of said membrane (2) on which there is also arranged a ballast (3) of ferromagnetic material which undergoes the attraction of one or more magnets (7) arranged on the cover (4). In this way the pressure switch retains the functionality of conventional pressure switches yet with a structure extremely simple to manufacture, which results in low manufacturing cost and high reliability, and makes simpler to adjust the intervention value and to set the restore value, allowing for an adjustment range of the latter which can even extend to zero. <IMAGE>
