I have two switches in my bathroom. The first controls two lights, the second controls a fan.
I would like to change it so that the first switch controls one light, and the second switch controls a light and a fan.
I opened the switchbox and am confused by the way it is wired. Here is a drawing (I did not draw ground wires, each switch has one):
My explanation of the picture (possibly bad terminology) is we have two neutral wires coming out of the box that are wire-nutted and pigtail connected to the top "traveler" of the switch that controls both lights.
Another pig tail comes out the bottom "traveler" and is wire-nutted into two neutral wires coming out of the box, and another pig tail connecting all four wires into the bottom "traveler" of the switch controlling the fan. A red "hot wire" comes off the top traveler and goes back into the box.
This wiring situation is not intuitive to me (I know nothing). I thought maybe the two wires at left were because there are two lights, but why are there two wires on the right for just the fan? And why are these switches wired together via the pig tail across the bottom? I expected to see two hot wires going to each switch, and no connections between them. How does the switch that controls the lights work without a hot wire going to the switch?
If it is the case the the two wires on left are for each light, can I move one of them to the cable nut on the right to have it be controlled by the other switch?
