Since some pics have been lost over time, I figure I'll add mine for reference.
I just bought an SW02 off of the auction site. The switch seems like a legit version and not counterfeit. However, I was disappointed when I discovered the switch didn't work. Did a little bit of research and came across this thread. This helped me tremendously and I was lucky enough that the threadlock wasn't too much of a bear to get passed. I did have to boil it for quite some time. About 15 minutes I think. Took it apart and discovered that one of the wires had broken off of the tabs. Soldered it back on (a little crudely because it was really tight in there), and the switch worked again. If you have an SW02 that doesn't work, this might be worth a shot.
On to the pics.
It's hard to see but if you look in between the boot and the shroud, you can see a delrin retaining ring. I didn't try, but I'm sure if you can somehow take out that delrin ring, you'd be able to take out the boot and shroud assembly.
Took some boiling, wrapping the end with paracord, griping gently but firmly with channel locks, and a good twist but I was able to get passed the threadlock with out any incident.
I just used some needle nose pliers to twist the keyed section of the assembly. No fighting threadlock here.
You can kind of see where the wire on the right is not making contact on the tab.
Judco switch. Didn't someone fit a Judco switch to a Z41 for a high-current reverse clicky switch? Can the same be done here?
Took the switch out of the assembly and that's when I discovered the wire not making contact to the tab.
Just needed to resolder to the tab and was good to go.
