How to Wire Two Light Switches With 2 lights with One Power Supply diagram

Thank you, Harold. If I am understanding your drawing correctly (and please forgive me as I am a novice, but willing to learn), then I need to replace the current 14/2 line with a 14/3 line from the powered light to the switch and use the red line to carry the power to the second light as well as pigtailing the grounds for the 2 switches. Is that correct?

I very much appreciate your time in making a clear drawing.

I am renovating parts of my house and the wiring is a bit complex. If you're interested, I can write you a mini-novel about what I've found and the thing I termed "The Everything Switch" (which is what one of these new light switches has taken the space of). My next electrical project will be restoring the power to the front half of my house...I am currently running 6 extension cords!!

That is correct. The white of the 3-wire takes power to the switch, the black (or the red) takes power back to one light, The red (or black) takes power to the other, thru the first ceiling box. Redesiginate the white to the switch as a hot by coloring each end of it black with a felt tip marker.

I don't show ground wires because they are not part of the circuitry and would make the drawings too messy. I assume every one knows that all grounds get connected together and to all fixtures and metal boxes.

Harold, in my excitement to get my lights back, I think I read your diagram wrong. The power coming in is 2-wire, but then I need to use 3-wire from the light to the switch and jump the power from the red to the second light as well as the second switch. I am going to print that out and take it into the attic with me (when the temps go below the 100s!).

Thanks for your help and patience.

Similar to cdnfullmoon, I have a switch that is end of run that controls outlet power in a bedroom. I want to add a second switch that gets power from the first to power a ceiling fan. I'm not sure that I can easily run a line from the switched outlet to the fan to using the wiring diagram posted by hkstroud.

Any other options?

Sorry but you must get a cable from the outlet to the ceiling or from the switch to the ceiling , no other way.

I'm going to have my attic roof fan, & 6 double florescent lights in my garage. I am go to install a 20 amp circuit with 12gauge romex out of the panal. What would be the best way to wire them if I want the switchs in the same box beside each other ?
Thank You

What is amperage draw of fan?

OK, but if the power is in as shown in the first drawing and the wiring from the switch to the lights are as the second drawing. How will the connections be then?
A diagram would be most helpful.
Thanks!

I have wiring in place for 2 switches, 2 lights with 1 power source going to one of the lights and a wire going from one light to the other. Each switch has wires going to their own light. How do I connect to have each light working on its own switch?
