イツチ。 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 electrical switching parts are provided in the lower body, A first reversing disk that reverses downward by pressure is installed on the top surface, and a first rod for operating the first electric opening/closing part is housed in an insertion hole provided in the center of the piston so as to be able to move vertically. A second piston with a second reversing disk placed on top thereof is housed in the lower body so as to be movable up and down, and the peripheral edge of the second reversing disk is attached to a holding piece provided at the bottom of the first piston. A second rod for operating the second electric opening/closing part is housed in an insertion hole provided at the center of the second piston so as to be movable up and down, and a rod below the second piston is provided with a rod that can be adjusted from the outside. A three-acting pressure switch comprising a third piston that is spring-loaded upwardly and is locked, and the second electric opening/closing part is accommodated in a notch provided in the third piston.
