Isn't bell/phone wire the same gauge as the wire used for the miniature X-mas tree lights?

Of course those are wired in series so there's probably not that much juice going through them.

Sparky66 - That's a venerable and interesting-looking switch. Neve seen an in-wall switch with front wire terminals before. I'd be leery about using one of those with a metal cover-plate. [Linked Image]

Did you put new wire/devices in there or did you have to close it back and leave as-is?
