I have 3 new can lights A, B and C.
I want to operate all on one switch. No Problems.
But I also want to operate B on separate switch alone.
How do I wire this up?
Please help

2 switches would be easiest.
You can do it with 1 DPDT switch with a center off.
Up(on) would be all 3 lights and down(off)would be the single light.
If you want to do it with 1 switch, I will see if I can post the drawing.
