Re: How to remove an OLD switch box?
There's another thing I'm seeing here... it looks like you have knob-and-tube wiring (individual conductors mounted on insulators, rather than bound in a cable with an overall jacket).
There are special considerations when working with knob-and-tube. It sounds like you might be replacing it all anyway, but if there's some you aren't be very careful working with it. Try not to disturb it, because the insulation can be very brittle. I've protected this type of wiring with heat shrink tubing when I've disturbed it.
