Check those switches they should have silver plate over copper.

I checked them out, here are some pictures for ya maybe they will help someone elses curiosity. These just happened to be on whatever I was taking apart so by no means are these all the push button switches out there:





Each contains a very thin copper plate, the contacts in the base probably contain no silver since the contact plate is not silver plated:



This is what I meant by transformers and small copper coils in plastic (whatever they are?) I throw them in my transformer bucket since they have the same or greater copper density ratio as a transformer, although the yard has recently started telling us not to put the high voltage flyback transformers on the top left in the bucket anymore they will only take them as light iron but they pay $0.20/lb for this stuff minus the large top left that would be $0.12/lb:



These are the copper goodies I smash and pull apart for easy #2 copper:



I removed the cover of a relay box and I can easy see tossing these in the transformer bucket same density ratio, I would pull that small piece of brass takes 1 second @ $1.60/lb. The contacts I am not sure about some people say some are silver, not sure what they would be:



Not sure what the heck these are but I find more of the yellows then these cans, I assume capacitors and resistor?
