Generally, I've taken the consensus as this: Use physical switches for very common, need to know where they are and have the physical landmark, with reliability being something of a second (since so much is computer controlled, but when it's that vital, they try to make said computer controls so redundant, like 4-5 independent computers polling, that if you lose the computer control, it's likely because something destroyed the craft already). Use touch interfaces for esoteric and menu selection functions, generally the sorts of things that you're never going to be in a position to need to select it hurriedly.
