Got my M6 switch apart part way and ????

What, if anything, should be used as lube/connectivity stuff?

It looks pristine in there... no obvious clue as to why it can be flaky.

Maybe a drop of something???

LPS-3 metal seeking lubricant (its a bit pricey, like $10 a 12 oz. spray can). You can find it at boating supply stores. Clean the contacts with some ScotchBrite and blow them off with air. Then spray them with LPS-3, let the lubricant sit for a few minutes and then wipe off the surplus. This should be good for years. I use it for MiniMag switches and to protect the aluminum checker plate on my shop trailer from acid rain. I hope this helps.

<EDIT> I just remembered, Beeman Airguns sells a metalophilic oil also, its called MP-5. It might be a bit less expensive (however I haven't tried it on electrical contacts). You might check your local gun shops.
