Is there such a thing as a multi-switch?

I think you have said it. You need what is called a selector switch with 3 poles if you want 3 speeds. Key words to shop are selector switch, not multi-switch.

three speeds yes but no five speed.

I can't think of a reason that wouldn't work.

The barn furnace has a blower motor that has (if memory serves right...) five speeds. Well, at least three, but pretty sure it's five. Is there a switch that would allow me to select the blower speed? Like a five point switch?
