VentLine kitchen exhaust fan )The above fan has 4 terminals:L,1,2,3 L is for Line (HOT). So I have 1 light and a 2 speed motor to hook-up to this switch ,I just need to rember where each wire went to each terminal------(I should have wrote it down.} The switch looks like the kind that you would find in a box fan---a squar shape switch with 4 terminals.
