The switch powers the two solenoids.
The solenoids are in a normally-closed configuration.
On the closed position, no current is brought to the solenoids so they stay closed. To close the valve, you first need to go on the active position for half of second so you can build pressure in the tube that goes from the intake to the valve.
On the active position, the solenoid on the right opens. Which basically makes the system just a cable from the intake to the valve.
On the open position, the solenoid on the left opens so the valve is simply disconnected from the system and since it's a normally-open design, it just stays open.
Cool thing is, it's not as loud as a muffler delete and the fact that the exhaust gases takes a third path, when the meet at the tip, I can't really explain why but the sounds feel smoother than when I had a muffler delete.
