Not if they still work it isn't!

Why do you say that ?

Because I've already tried it and learned the hard way!

A pay-per-view article - very useful!

Pardon ?

Graham
When I clicked on the link to the pdf document it took me to a window that
quoted a price to view the document.

Does anyone know if Evolube (possibly Elvolube) still exists?

Apparently so:

http://www.ecllube.com/003products.aspx

Haven't found anyone selling it in small quantities, but the
manufacturer
can presumably direct you to a distributor.

Yes - my google search found several references to that family of
automotive
lubricants, apparently an assortment of grades in a variety of
colours.

Mostly extreme water resistance and greases that increase in
viscosity in
response to shear (probably not very good for "wiping" contacts!).


Looking at the ECL products info it would appear that Evolube is
not
the best choice for switch contacts. Rheogel 283 and Absolube 411A
are
suitable for this use however.

Its fairly obvious that I got the name wrong, its many years since I
last
saw the product in a workplace and the tube of it that came into my
possession was so crumpled the label was barely readable - I vaguely
recognised what was left of the livery on the tube and could just
make out a
few lines of instructions to thinly coat electrical contacts.

The reply from Fred Abse correctly names the product but googling
gets no
hits, so it seems likely the product is no longer available. Your
suggested
alternatives are well worth following up - thanks.
Ian, if you go to the link for ECL (as provided by mc), you will see
that Evolube IS one of their products - as are the two I suggested.
Evolube IS still available, BUT according to the applications listing
for this product it is not recommended for switch contacts.

Ian is trying to tell you that silicone grease is an insulator and is
not suitable for use on switch contacts.

Silicone grease was banned for use anywhere near telephone exchange
relays back in the 1960's because it was discovered that the grease
"migrated" from the point of application and eventually onto the relay
contacts, which then refused to pass signals. Silicone grease should
never be used on switches or switch contacts for this reason.

IIRC, there was a product back in the 1960s called "Elvalube". As I
recall, it was made by Gulf Oil, and was just a pure mineral grease
without additives.

When I last used the stuff in a job was many years ago and a long distant
memory, and the tube that since came into my possession was so crumpled the
label was all but obliterated, but now you mention Gulf Oil I think you may
have hit the nail.

Perhaps similar; I have a 50+ yo can of No-Ox made for terminals on
battery strings. The only label data is "Bell System Property" but it may
be the same thing as the "No-OX-ID Special" at sanchem.com; that site
says it's cosmoline-like.
