As Joe described, we are putting resistors (like 10K or so) in series across the terminals of a rotary switch. We have used Radioshack rotary switches before, but we now use these Electroswitch ones:

They have 12 positions but we only use 6 positions and use 2 of them (6 * 6 = 36 auto selections, we rarely need more than that ).

Joe's suggestion of a pot with 10 detents is also a good idea. They are cheaper and much easier to solder. We'll stick with the rotary switches to avoid the very minor risk of setting them in between detents.

Another interesting new feature to use for auto mode selection is the Driver Station LCD. During Disabled mode, we pint a short name for the Auto routine on the LCD screen so it can be confirmed.
