Actually this is really one of those situations where I'm trying to force a solution to a problem - I picked up a bag of these switches for a couple of dollars and now I'm looking for a use. The application is just to provide a knob to control the duty cycle of three different PWM module. The easiest solution is just using a pot and an ADC channel - three pins, some case commands and it's done.
