Pneumatic LEGO parts are specialised components to perform various actions using the principles of air pressure.
The pneumatic switch has three valves or ports on them, and a axle which controls which of the ports are connected to each other.
Switch in
- Right position: left port is open, center and right port are connected.
- Center Position: left, center and right port are closed
- Left position: left and center port are connected, right port is open
When a port is "open", all the air will leak out as fast as it can. When a port is closed, no air can enter or leave that port. When ports are connected, air will freely travel through the valve between those two ports.
