Membrane pressure switch

A method for adjusting a switching point of a membrane pressure switch, wherein the membrane pressure switch comprises:

• a housing, in which a deformable membrane is arranged, at which a mushroom shaped thrust element abuts, which is movable by the deformation of the membrane;
• and
• a microswitch, which is arranged in the housing opposite the mushroom shaped thrust element by a fixing disk,
• characterized in
• that the fixing disk is provided with an external thread, which is screwed into an internal thread of the housing in a mounted state of the fixing disk,
• and wherein the method comprises:
• Applying pressure in a pressure chamber of the housing and deforming the membrane and moving the mushroom shaped thrust element into a switching position;
• Screwing the fixing disk with the microswitch fixed thereon until the microswitch is switched by the mushroom shaped thrust element;
• Preferably indicating the switching of the microswitch;
• and
• Screwing a counter screw into the fixing disk until an end surface of the counter screw is supported on a bottom surface of the housing and thereby the internal thread of the housing and the external thread of the fixing disk are jammed relative to each other to fix the fixing disk and thus to fix the switching point.
