I would like to replace a single pole switch with a double switch. There is one light attached to the switch, and I would like to move that to one of the new switches and have another light attached to the other switch. The lights should operate independently; one in the family room, one in the dining room. Below is the current configuration of the existing switch. The only difference between the picture and my situation is that the power from the existing light comes through BX cable, and I will be using Romex (12/2?) with ground. I presume I can connect the grounding wire to the grounding screw in use now with the NM.

Assuming the picture below is accurate, how do I wire the new switches/fixture to take the power from the existing configuration? (Or, what changes do I make to the drawing to make this work?)

It SEEMS to be simple, but I really don't want to overdose myself on electricity.
Thanks for any help that can be offered.

See the black wire marked " power in from source"
which goes to the bottom of the switch ?
Splice into that wire with a wire nut.
that goes to your black wire.

You also need to splice into the white bundle of wires
this is your neutral. white.

Take these two wires to your new position.

Combined with his comment about power from the light in a BX, I am not sure
what he has.

I think he needs to pull the switch and look at it. Does it have 2 cables and only the blacks on the switch ? Or is it one cable with a black and a white on the switch.

The two black wires connect to the switch. Still would like an answer regarding grounding wires (see original post).
Thanks for your responses.

If you want to take three wires to your new position-
1 = take the new black wire from the bottom black wire of the existing switch,
This is your HOT supply.

2 - Take the new white wire
from the white bundle already in the existing position.
you may need to use a larger wire nut
This is your NEUTRAL.

3 -Take the new green wire
from the green bundle already in the existing position
again you may need a larger wire nut.
this is your GROUND.

Thanks for the help.
Due to impossible construction concerns, I find I am not able get wire to the switch, so I've been forced to re-think the project.
I will be trying to provide another challenge on another project...same construction, so I may have the same problem.
In any case, I will post a new request for help as soon as I can figure a way to create a decent diagram and explain the problem clearly.

You will have to cut some access holes in the wall to pull the wire from the box to where you want it to go. Same with cutting holes in the ceiling if there is a finished floor above.
