Hmm.  Jay, you're in the same place I was a  month or so ago.

A four position rotary switch would take up four button inputs (key presses) on your interface controller (EPIC).  A six position switch, six button inputs.  Hairy code would be required to detect one detent moves in either direction.

OTOH... A rotary encoder would only send two different key presses to your interface controller, no matter how many actual positions (detents) it has:  one for a clockwise turn of one detent and one for a similar counterclockwise turn.  

Another way: A rotary switch only sends (makes) key presses.  It's dumb.  A rotary encoder is smart - it knows which way it's being turned, and sends the key press appropriate for the direction of turn.

  Can't you just use a rotary switch?  I never really bothered to look for the difference in encoders and switches.

  What are the advantages of rotary encoders and why would I want one?


         Virtually any knob in your pit that you turn to make adjustments (as opposed to a potentiometer that you would turn to adjust volume or brightness) such as a radio tuner, HDG or OBS knobs, the Kohlsman knob on the altimeter, the course, speed and altitude setting knobs on the autopilot, transponder code selector, etc etc etc would all be rotary encoders. 

         There are alternatives such as Knitter switches, but as a general rule, anything you want to be able to 'dial in' needs to use a rotary encoder.
