The photo below is from my comment on my post on the "Flashaholics Anonymous" Facebook page, September 18th. Other photos are there also. It shows the tools and parts used to replace the switch. I also tested the switch and connections with a multimeter.
1) Unscrew the ring holding the button and switch with snap ring or needle nose pliers.
2) Pull the switch out and unsolder it. I took a picture first so I could reattach it if needed.
3) Solder the two black wires together. I put some heat shrink tubing off to the side on one of the wires before soldering, and the moved it over the soldered connection and shrunk it in place with a heat gun. This prevents short circuits and makes the connection more secure. (It's better than electrical tape)
4) Put the battery in and test the fan by touching the red and white wires together. (An alligator clip can be used)
5) Find a switch small enough to fit in the about 18mm hole. I improvised with Halloween LED candle switch because it was black and could be cut with diagonal pliers and filed to the right size. other tealight candles, toys or devices with small switches could be used.
6) Place heat shrink tubing on the red and white wires, slide it to the sides, and solder the wires to the correct connectors on the switch. Slide the tubing over the connections and shrink it carefully with a heat gun. (I overheated it on the first time and the switch started melting, but fortunately the candles were a two pack) Holding a hot soldering iron close to the tubing without touching it can work also.
7) Test the switch, and then tighten it in place with the original threaded ring. Done.
