That's what I thought he meant when he asked his question. I just find it odd that someone would want to manually turn a compressor on when the pressure switch does it for you. Experience has shown my team, that having the compressor constantly running will dramatically drain the battery, which is why FIRST supplies the pressure switch. Just make sure that there is no leaks so the compressor isn't on all the time.

P.S.- It's also a good idea to charge your system before a match. Have an extra battery for turning the compressor on to charge up your system, so the compressor doesn't run during autonomous
