Yes, except fans are pretty high current inductive devices, and will likely burn out the contacts on most switches in pretty short order. It's probably easier to size a relay than a switch to that amount of current draw, although I suspect Lynn knows something I don't <g>. Additionally, the relay can be spec'ed to break-before-make (that's the way typical relays work), whereas as a switches contacts get tired they can actually have NO, COM and NC contacts connected together all at the same time during the switching cycle... with the shunt applied across one side of the DPDT switch that's a recipe for a dead short and a blown breaker. Been there, done that.
