Today I replaced the switch on my wife's JadeFire for exactly that reason (and the fact that it was the wrong color). If you buy the illuminated AV switch from thecustomsabershop.com, it comes with a nut that holds it in place. From outside the hilt, it is identical to the switch used by SaberForge.
If you're not opposed to dusting off the old soldering iron, I highly recommend it. Cheap and quick. I didn't even have to cut new wires.
