If you don't want to void your warranty, you need to send it into UltraSabers for them to fix it.
So, here's what happened. I've accidentally done this before when building. Someone was building it in a hurry and wasn't mindful of where the wires were and that there was enough slack when they put the switch in, so stuff got trapped in there when they jammed that switch in. It's actually not that difficult of a fix, but as I said disassembling the electronics yourself even a little voids your warranty. All you have to do is heat up the glue to soften it (heat around the switch with a heat gun, don't directly heat the switch) until you can pull the switch out. Then bring the LED module forward and have it "hanging out" the front of the body section with the quick connects easily accessible. (obviously, have it laying on a table or something) Also, make sure you have room to get your battery pack and all that back out the other end, it's a fine balance thing. Heat your glue back up so that it's almost runny, then put the switch back in. Lay the hilt on the table switch down and leave it a while so that the glue will pool back around the switch and harden around it as it cools. Then you should be good to go, you should now be able to put the LED and other stuff back in and then you'll be able to pull your LED back out and disconnect/swap it when you need to.
Though, if you want to maintain your warranty and/or you're worried you'll mess something up, just start the process of sending it back in for them to do it. That's probably what one of their techs will do, and it will still be warrantied.
