Dielectric Grease

Is it desirable to use any sort of dielectric grease on the moving
parts that support the contacts inside of an enclosed switcher?

The encasement isn't exactly air-tight, but the action of making and
breaking involves the Phosphor-Bronze or Brass contacts being wiped
mechanically before and after they come together, so contact oxidation
shouldn't be an issue, but I was thinking that adding dielectric
grease between the moving parts that touch each other would help in
keeping dirt out and reduce friction.

Or is there a better product for this?

Thanks.

We're using Dow Corning #4 (aka DC4) for such things, on aircraft cannon
plugs after cleaning. It prevents the oxidation that eventually
interrupts current flow and also aids in re-/dis-assembly

That looks just like what I need.

Thanks a lot.
