Andy,
I don't know if the pot would work as great as the switch. I have used these pots for volume controls and they are not repeatable as the switch it. The detent is accomplished by a disk with bumps on it. (just stamped out part)
They also have an 12 position switch that looks identical to the Radio Shack part. We put a round knob and it is not easily bumped. All it selects is a different auto mode. The program looks at the switch value (voltage) and jumps to a different routine on that basis. We have used this method for three years now.
