I was in the process of switching cases to fix a broken hinge with one of my Nintendo DS Lites. Everything went as planned, placed the battery against the prongs and it powered on and everything. All I had to do was replace the buttons. When I was placing the L button, I noticed the SW9 L switch was dangling by a thread (no idea how it happened) I tried securing it back to the mobo with a small piece of tape, and it snapped off. I really have no experience with soldering to circuit boards, nor do I even know if this part is supposed to be soldered. Eeshops sells the part for just 99c, and says "Easy to install. Needn't to pay for high repairing fee." However I can't find anywhere that actually explains how to install the switch. All help appreciated.
