Two Lights, Two Switches, One Power Source

Hello,

I am looking for info on how to wire an overhead light and switch in each of my two upstairs bedrooms. Here is what I have right now:

Bedroom #1

Power comes from panel, through attic, to overhead light (12-2)

Bedroom #2

Power comes to overhead light from light in bedroom #1 (12-2)

Right now there are no switches to turn off the overhead light in either bedroom. Ceiling fans with remote controls were used by the previous owner.

I would like to add a switch in each bedroom to control the overhead light in each room. I have searched for a wiring diagram, but have not found anything for my specific situation. Any help is very appreciated.

Thanks,

Lamont

Either you will need to run additional cable or use a conventional remote or a piezo electric remote switch. Lightning Switch | PulseSwitch Systems, LC

I would like to run additional cable, but I am unsure of what connections to make. I looked at a bunch of wiring diagrams online, but couldn't find anything that fit my exact situation. From my research, I believe I need to run 12-3 cable to my wall switches, but I am unsure. Do you know of any wiring diagrams to fit my situation? Thanks for the response.

Since you just want a ceiling light in each room, no fans, you don't require 12/3.
Here's what I advise:

Keep the existing cables as they are: #1 ceiling from panel, #2 ceiling fed from #1 ceiling.
To add switches:
Run a cable from #1 ceiling box to new switch location.
Run a cable from #2 ceiling box to that room's new switch location. (12/2)

You can post back for wiring after cables are ran. It's pretty easy.

Use plastic old work boxes for new switch locations. The hole you cut for old work boxes gives you some room to work inside wall when pulling a new cable down.

****Edit - run 12-3 w/g down to switches. This will be up to current code. The switch wiring will still be simple.

Thank you for the response. I will definitely use 12-3 for the switches. I have mounted plastic work boxes for the switches and drilled holes through the top-plate for the 12-3 down to the switches from the lights in the attic.
I am running into trouble when it comes to connecting the cable for the switch (12-3) to the existing wiring for bedroom #1's overhead light. And then the switch for bedroom #2. Can you give me a brief rundown of what should be connected to what? Thank you again.

Actually if this is a switch loop to meet 2011 or later NEC you will need 3-conductor cable to meet code.

Ceiling #1 has source power.
- Connect white source to: #2 ceiling power white; switch white; light fixture white
- Connect black source to: #2 ceiling power black; switch red
- Connect black from switch to light fixture black
- #1 switch: Red to one terminal, black to other terminal, white capped

Ceiling #2
- Connect white from #1 ceiling source to: switch white; light fixture white
- Connect black from #1 ceiling source to: switch red
- Connect black from switch #2 to light fixture black
- #2 switch: Red to one terminal, black to other terminal, white capped
