After confirming that the positions in the vertical direction are aligned with each other, or if they are misaligned, adjust the mounting position of the switch 1 to make it match, and then install the hydraulic / pneumatic cylinder in the device.

Further, when the end of the cylinder stroke of the piston does not become the operation end of the piston when the oil / pneumatic cylinder is installed in the device, for example, as shown in FIG. 7, the oil / pneumatic cylinder is installed in the device. The position of the operation end of one of the pistons 3 (right side in the drawing) when retracted is left from the position of the end of one of the cylinder strokes (right side in the drawing) due to the mechanism or stopper of the device not shown in the drawing. In the case of the position of Amm, before the hydraulic / pneumatic cylinder according to the present invention is assembled into the device, the cylinders at the switch positioning marks 10 and 11 displayed on the outer surfaces of the switch 1 and the cylinder tube 5 are provided. After adjusting the mounting position of the switch 1 to the left so that the lengthwise distance of the tube 5 is Amm, the hydraulic / pneumatic cylinder is incorporated into the device. Then, in any of the above cases, when the piston 3 reaches the end of its operation, the switch 1 is turned on by the magnetism of the magnet 4 provided on the piston 3.
