I ended up just routing another power source to the same switch box and connecting it to the single pole switch. I don't think what I was trying to achieve was possible. Thanks for the input!

A question for Ron:

Looking at his diagram, it appears as if the neutral is switched, not the hot. Is that proper?

The only neutral is the one white wire across the top of the diagram going from 'power' to 'light'.

The other white wire is not a neutral. Don't let the colour of a wire fool you.

That's correct. I have no idea why the white wire (hot) was wired to the black wire, that confused me for a long time too when I was trying to understand where everything went, but I stopped trying and just let it be since the original switches all worked.. heh.

A white wire can legitimately be used as a hot in certain situations. It wasn't done in error.

In addition to the example above, a "switch loop" will also use the white as a hot.

240V circuits will also use white as one of the hots (there is no neutral in a 240v circuit).

I think technically the white should be re-marked as black by wrapping black tape around it or using a permanent black marker, but it's often not.

It's allowed not to remark the white wire in a switch loop when it is used to feed the power to the switch. That is the white wire to the switch should be connected to the black wire in the fixture box.

Ron and Greg, thanks for correcting my oversight. Whenever I can, I use a red wire for such switched hot lines.

The only problem is that there isn't a cable with just black and red (or it's rare). And if you run 14-3 and just cap off the white, then it's a waste of money.

Although it's probably good to have the neutral at the switch nowadays (for timers, dimmers, etc), so in a switch loop you should probably use 14-3.

But I've never seen a cable with black, red, and some other colour that would be needed for the diagram above.

NEC

200.7(C) Circuits of 50 Volts or More.

The use of insulation that is white or gray or that has three continuous white stripes for other than a grounded conductor for circuits of 50 volts or more shall be permitted only as in (1) through (3).

(2) Where a cable assembly contains an insulated conductor for single-pole, 3-way or 4-way switch loops and the conductor with white or gray insulation or a marking of three continuous white stripes is used for the supply to the switch but not as a return conductor from the switch to the switched outlet. In these applications, the conductor with white or gray insulation or with three continuous white stripes SHALL BE PERMANENTLY REIDENTIFIED to indicate its use by painting or other effective means at its terminations and at each location where the conductor is visible and accessible.
