Cleaning up an old rotary mode switch used for 5v logic levels. It has some kind of grease in it.
…which has always confused me: grease is an insulator (well, the grease in this switch is—just tested and it’s infinite ohms).
I read that dielectric grease is good to keep contacts sealed against the elements that have high physical pressure (which overcomes any separation provided by the grease) but that signal and other low voltages grease is contra-indicated.
What say y’all?
Thanks.

Can we summarise this thread by saying -
Any grease is better than no grease,
Grease is more easily pinched through than corrosion. It extends the
life of sliding switches by reducing friction.
