Here's a lubricant, stored in my toolbox, I'm trying out on a zoom-able LED flashlight that uses a ball bearing and spring along with threaded assemblies. Seems to make the moving parts function a little better.
This is a lighter type of grease lubricant, originally made for electrical switch contacts in the automotive industries (switches, sockets and harness connectors).
Back of tube shows: Excellent oxidation resistance and compatibility with metal, plastics and rubber.
Lubriplate DS-ES Part No. LO137-086.
I've read of at least one flashlight owner using it on their Maglites to lubricate the internal switches, mechanisms, threads, springs, etc.
Perhaps could be thicker in consistency. The flashlight did have some small areas around the zoom with a very small amount of what appeared to be silicon grease.
For electrical switches and contacts this lubricant works excellent. Doesn't gum up and will last a long time.
