I have a room where I need 2 ventilation fans. One will be a regular bathroom fan, the other a much smaller fan powered through a timer in an outlet. Both will be vented through the same duct to the outside and I don't want them both running at the same time. Thinking of using a 3-way switch: up to turn on the bathroom fan, down to power an outlet. The outlet will be powered most of the time and only disconnected while the bathroom fan is on.
Not a typical scenario so wondering if there are any problems (code or otherwise) I could run into with that configuration.
Thx

They make double switches that fit in the same box a single switch would. They come in two and three way combinations. This way you could use the three way as a selector and the other if you want both off. You could also control each individually.Also while you are at it consider when one fan is on will it exhaust back through the other fan? You may have to put dampers on the ductwork to prevent this.
