For an attic exhaust fan the factory pull-chain switch is sptt, with three
output wires to the fan motor corresponding to the three speeds.
The pull-chain switch is on factory j-box attached to fan. We will wire and
supply a new switch at a more accessible location. So we will run 12-4 and
get a sptt fan control switch for wall mounting.
However, I was wondering: What if we ran 12-2 and wired to the highest speed wire for the motor, then used a typical variable speed fan control with only one output wire ?
