Can anyone recommend an electrically conductive grease to keep electric contacts corrosion free?

Does this stuff fit the bill?
NO-OX-ID A-Special Electrical Grade

Thank you for that link. Sounds amazing. At $4 shipped for a small tube I just might give it a try... Anyone else thinking pressurestat contacts?

Yep, that's what it's going to be used for.

The product that is being discussed was, I believe, developed when corrosion problems between aluminum and copper conductors occurred in the mid-sixties(?). When aluminum wiring began appearing in homes, there were many instances of overheated outlets due to increased resistance/poor contact between the wiring and the outlet terminals. The application of this product (or similar) was code-mandated.

I have never heard of any product designed to be applied to switch contact surfaces, other than contact cleaner aerosols. The typical arcing that takes place between contact surfaces on stand-alone pstats is taken into consideration during the design phase when anti-corrosive materials are plated onto the contacts.

At the very best, I'd be extremely wary of applying this to any contact surface that sees normal cyclic operation. Why not call the manufacturer and see what he has to say about this specific application?

Contacts are engineered
They have minimum and maximum current, voltage and power ratings.
They are cleaned both by physical movement and electric arcing.

Use 'goo' at your peril

I tend to agree with CafeIKE, but if I was looking, I'd start with the company that makes Cramolin and Caig Laboratories, seems to be http://store.caig.com . No idea if the stuff works, but they've been around for a really long time and before high end audio discovered their products and they found consumers, they mostly targeted big industrial uses.

As others have said, I'd be reluctant to use anything on arcing contacts like those in a pressurestat, because the arcing would reduce almost anything to ashy gunk sooner or later. But for contacts that don't arc, I've had extremely good results in many varied applications over many years with Stabilant. Particularly germane in espresso machines, where moisture is a problem, but in Randy's case also good for undersized headlight connectors in old BMWs.

Best,
David

dielectric-grease

this might be what your looking for avail at most automotive and electronic shops

dielectric grease is non conductive.

Got it -- no grease on the pressurestat terminals!

Thanks for the help.
