Wiring Diagrams for Wiring Wall Switches

I’m adding a wall switch to a light that has a switch on a cord out of the wall.

1. The switch is going into another box which has power as well with a switch to another light.
2. I need to know if I should go with power from the box or from the light.
3. Which would be easier and detailed wiring diagram etc.

Not three ways!

Thanks for your electrical question Michael.

How to Add Electrical Wiring for a Wall Switch for a Light Fixture

• Michael, you only need to switch the power or hot side, so a 2-wire cable may be run from the existing power source of the light fixture to the location of the new switch.
• The switch is of course is wired as  power in, and power back out.
