    You would still have to either hook up an additional momentary switch to change patterns, or choose a pattern and stick with it. As for which switch to use, find out what the bar draws, if its less than 10 amps, go with a 10, if its more than 10 you could either go to the 30 amp switch or put a relay in the circuit and run it off a 10.
