How did you manage to unscrew the extension from the switch module?
Thanks!

No thread locker, just old and not-well-lubricated threads.
I have the same set Zeiss is selling, and the first time I used it, it gave me cramps getting the parts apart.
Since it's been properly lubed, it operates flawlessly. I use diamond nano, and it works beautifully.
