How to control the protruding length of the cylinder through the button switch

1. When the button switch is pressed, the solenoid valve will open, so that the compressed air in the cylinder will enter the convex cavity of the cylinder, and the cylinder will extend until it reaches the preset length.

2. When the button switch is released, the solenoid valve is powered off, the compressed air in the air path is released, and the spring of the cylinder retracts the cylinder to its original position. In this way, the extension length of the cylinder can be controlled by pressing the button switch.
