Hi, so my first saber ended up not functioning for some reason, at first I believed it to be the battery pack I kept gluing and taping back together just broke with wiring. Though now looks like it was my switch, because when I opened it, the internal spring and pieces in it fell out, I'm not quite sure how to put it back together so, if someone could please tell me how to reassemble it and bring my first saber back to life it'd be much appreciated.
