Relays on low grade boards

Thanks, I'll have to go look at my stash. Ran across a few inductors/coils recently that had shrink tubing over them that made them look like capacitors. Only thing that tipped me off is they weren't smooth cylinders. The sides were a little wavy. Just something else to watch for. Looked similar to this:

SILVER CONTACTS??? I have been throwing these into the bin with the brass or stainless. I will have to be a little more careful. Can you post a pic of what part is actually the silver plated part please. I will be saving these to precess them. I love precious metals for free!!

Thanks Gravitar. That's a much better picture than my camera will take.

this year a few thousand next year maybe a few hundred. as i am sure we all know the metals market can jump or drop at anytime.

and these contacts are found where and on what before the look like the above pic.

I have been saving up contacts from relays for about 6 months. So far I have over two ounces of silver contacts, 4 of silver/copper & 1 of silver/magnetic.
I guess that the silver/magnetic are either cheaper, or more valueable than the others, depending on the individual contact.

In the pic above, you can see the contacts, they are all silver/copper contacts. Normally the centre contact is all silver (because it contacts on both sides), just depending on the manufacturer.

The little relays you find in microwaves are easy to pick apart & they are all different deon their use.
The one I have in my pocket I just found in a washing machine, it has a silver bar on each contact surface.
The teflonny looking relay I found had three nice solid silver contatcs. Most of those relays will have silver/copper contacts.

The better contacts will be in, expensive industrial equiptment (sometimes gold), often opened & closed switches - clothes dryers - washing machines.
