I have no idea whats going on in those boxes Hemingray, but i think the 220 recept is for A/C I wouldn,t think it is switched. wouldn't this be in violation of voltage seperation.
I'll bet money on that switch carrying 240v or so for that outlet. (or the outlet only supplying 120v) I don't see any other EMT or wiring runs to that outlet other than from that switchbox below.
