The pressure switch automatically turns it off when full and turns it on when empty. You do not need a secondary switch to aid this switch. If your compressor is turning off too early, check to make sure that the pressure cutoff is right and not low. That can typically solve many of these problems. If you still keep having these problems, check the FRC manual's section on how to set up the pneumatics circuit. Use that as a guide for your current pneumatics circuit and fix what you see isn't working properly, or differently affixed. That will get rid of most of your problems!
