Dielectric grease and conductive grease are both very difficult - nearly
impossible - to find in New Zealand, but I have done quite a lot of homework
on them preparatory to getting some.
They are NOT the same. In fact, they work in OPPOSITE ways
Dielectric grease as I have come to understand it is not a lubricating grease,
but protects surfaces that would normally conduct, from oxidation and other
forms of corrosion and fouling. It (they - there are a myriad of forms of it)
seems to be an insulator. So sliding contact surfaces are protected from
fouling that would prevent them from conducting.
Conductive grease seems to me to be a dangerous compound to have on a
rotating switch - slider.
It is a kind of grease that is laced (filled) with metal (or other conductive)
particles, so that the grease wherever it is, is a conducting surface. As I
understand it, if you coat a surface with conductive grease, the whole of that
surface will conduct electricity, even if before it would not.
And that is NOT what you want with a rotating switch.
