Help! Reverse clickie won't screw down into tailcap Lumapower M1

So I just tried swapping out the momentary switch with the reverse clickie using the guide at batteryjunction.com (http://lib.store.yahoo.net/lib/theshorelinemarket/Switching.pdf). Problem is the clickie switch gets jammed after a couple of turns into the tailcap.

That's as far as I can get it before it gets stuck.

Any ideas on what can be done?

Update - Threads and o-rings cleaned and lubed!

This is the first light I got that has something that isn't clear on the threads...

Lumapower M1


Any idea what that stuff is? I generally use Nyogel 760G on all the threads of my lights but not sure if I can on this one.

I have an M1 Hunter and mine didn't look like that. Just clean the stuff off with isopropyl and apply your Nyogel 760G..I use Nyogel on my M1 and it works fine!

That sludge was on my MRV. It made the operation stiff as it hardened over time. As recommended, use IPA to clean it off and replace it with a quality lube for flashlights (I used Krytox).

Thanks for the help guys! :twothumbs

Cleaning that stuff off this very moment!

Re: What is that stuff on the threads of my flashlight?

Is is possible that it is a reaction between two dissimilar metals creating some sort of metal oxide?

All threads and o-rings cleaned and lubed!



I'm assuming this is normal...

You just removed the conductive crease, that Lumapower applied for better electrical contact...
