The switch levers in contact with the grease are "live", I have tried
clear silicone grease in the past but it creeps and contaminates the

Sounds a bit like the Finish Line grease used in bicycle wheel
bearings. It's a synthetic grease packed with micron teflon
particles. I've used it on a number of things quite successfully,
having bought a large tub which would outlast my bicycle use by
a few lifetimes. (I've subsequently seen it in small tubes;-)
