When pressure is applied from A, the piston moves to B, causing the shaft to rotate clockwise. At this time, the magnet B goes out of the movement range of the auto switch B, causing the auto switch B to turn OFF. Furthermore, the piston moves to the right, causing the magnet A to enter the movement range of the auto switch A. As a result, the auto switch A turns ON.
