Switchgear

Postby Uncle Nick » Wed Nov 29, 2017 5:40 pm

Hi all, as it's freezing in the garage I've brought the (non-working) switchgear into the house to strip. I've separated and cleaned the contacts etc, which were very mucky with a thin black grease material covering everything. I've cleaned that off and lightly sanded the contacts, which appear ok. I suspect that the black stuff may have been a light oil that has protected the contacts but then ground accumulated dirt into a paste, until the contacts were insulated and stopped the switch from working.
So my question is, what type of oil or grease (if any) should I use on reassembly?
Thanks.
Uncle Nick

Yes I think that it may be WD40 to blame.

I wonder if contact cleaner spray would be any good?

Thanks for the help guys. I've put a thin smear of silicon grease on the moving plastic parts but would like to try and prevent corrosion of the brass connections as well if possible.

I've never heard of a dielectric grease, I'll have to have a Google!

dielectric grease a common use is when mount a power transistor to a heat sink
but not wanting an electrical connection
