In a pressure switch, a diaphragm is airtightly fixed between an upper body and a lower body having a pressure introduction port to form a pressure receiving chamber in the upper body, and first and second electric switches are provided in the lower body, A perforated piston having a first inverting disk that inverts downwardly mounted on the upper surface and a second perforated inverting disk that inverts upwardly mounted on the lower surface is housed in a holder so as to be movable up and down, and the holder is accommodated in the lower body so as to be movable up and down, and the middle part of this holder has an actuating protrusion that inverts the second inversion disk upward, and a cylindrical first rod with a head in the center that can be moved up and down. A movably mounted guide part is provided, and a disc spring having a hole inserted through the guide part is hung on the lower body wall, and below the disc spring are the first and second electric switches at different heights. The upper end of the elongated second rod passes through the hole in the piston, the second reversing disk, the first rod, and the first electric switch, and the upper end of the second rod is fixed to the first reversing disk, and the lower end is fixed to the first reversing disk. A three-action pressure switch comprising a second electric switch and a lower end of the first rod in contact with the first electric switch.
