<p>A diaphragm metal membrane pressure switch particularly for the opening/closure control of electric circuits. The pressure switch comprises a pressure switch body (2), in which there is a chamber (3) which is connected to an intake port (4) which can be connected to a duct for feeding a fluid. The chamber (3) is delimited by a diaphragm metal membrane (5) which can be deformed as a consequence of the pressure variations of the fluid within the chamber (3). The membrane (5) faces, with its opposite face with respect to the chamber (3), a contact element (6) which can move, as a consequence of the deformation of the membrane (5), with respect to the pressure switch body (2) in order to act on a switch (7) which is associated with the pressure switch body (2). The membrane (5) has, in a central region, a hole (8) at which a connecting element (9) is connected which blocks hermetically the hole (8) and can engage the contact element (6).</p> |
