First and foremost. I sure am glad to see that resistor question gone. I sure didn't mean to start such a big debate.

Anyway what kind of lube is appropriate for the sliding contacts on the pushbutton assembly of my Stromberg Carlson 340H?

There was something white in color there but it was cleaned off while cleaning the whole assembly. It works but sure feels like it needs some kind of a lubricant there to make things work more smoothly.

Thanks,

And I promise... No more ohms law for a while.

Johnny,
A light coating of silicon grease will work, (even the contacts) but I'm sure there are many spray can products that might be easier to use. I use the silicon grease, bacause I purchased a large tube for cheap years ago.

I do agree with Marv. If you are going to buy some lube though, I would say that Green TV tuner lube is very good for contacts and slides. It does not seem to dry out or cause any problem.

:Thanks guys! Just wanted to make sure whatever I was using didn't have conductivity questions. The contacts were originally lubed so what ever was used didn't interupt the conductance of the contacts.
Thanks again,
Johnny

Another point on lubricant use. Since almost all lubes collect dirt, you should use it sparingly. Just a tiny amount on friction points where metal meets metal is all that is needed.
I have seen overlubed radio components that turned into huge dust/dirt balls.
My $.02.

Without thinking, I used a wonderful lubricant for guns called Gunslick on a stepping switch at a radio station where I worked. It contains graphite. Graphite conducts. Don't use anything that contains a conductive material anywhere electricity. This is from one who has been there.

Johnny,
In addition to my prior post, there are silicon sprays, large and small that comes with a small tube to make a long nozzle. This may be helpful for lubrication only, but wouldn't think it would be a contact cleaner like TV tuner stuff. I've used silverware cleaner dip solution for cleaning contacts that are easily accessible, but a warm water rinse is required to weaken and deactivate the chemicals, then air pressure to blow dry.

Dielectric grease is basically silicon grease. It works well. Seems that most modern controls are lubricated with this stuff. It doesn't break down like natural oils and greases do. (or, rather, perhaps silicon oil is natural, since it comes from somewhere on this planet (I think), but I mean petroleum based lubricants)

Anyway, I do agree that silicon grease is good for this purpose. It's great for volume controls, too, because it doesn't migrate or conduct electricity. As I've posted in length elsewhere, the common practice of spraying WD-40 into a volume control leads to problems down the line due to bits of carbon migrating through the WD-40.
