ストン位置検出スイツチの構造。 When fluid is supplied into the cylinder, the fluid pressure causes a piston, which is slidably fitted in the cylinder, to be attached to the power cylinder for sliding movement, and the piston is generally referred to as the piston. A movable element that is movable in the axial direction is moved through a push rod that moves back and forth concentrically, and is brought into contact with and separated from the terminal bar, thereby bringing the contacts provided on the movable element and the terminal bar into and out of contact, respectively, and turning on the switch.・The mover is configured to turn off, and the mover is provided with a first coil spring for contact with the switch, and the push rod is provided with a second coil spring for returning the rod to its original position. A structure of a piston position detection switch for a power cylinder, characterized in that a piston position detection switch is arranged.
