The long insulators hydro uses on the high tension power lines are Lightning Arrestors inside they are full of copper discs with some brass.
The old electric trolley bus's have a lot of large electrical contacts, which I'm hoping are platinum alloy. A presumption on my part which I arrived at due to their heavy duty cycle being used 24/7/365.
Smaller contacts, inside electric water heater thermostats, electric stove rheostats, refrigerator motor start relays. washing machine motor start relays from the General Electric models.
Recently came across two commercial electric hot water tanks each has nine elements combined as three then hooked up to a relay, then one big relay.
Stripping old single phase electric motors for the copper, don't forget the motor start / run switch have contacts.
Three phase electric motors have an overload relay which would have precious metal contacts for your stock pot.
Electric circuit breakers another easy find.
Thermal Disks from dryers, have nice contacts, plus a bi metal disk.
Manitoba Hydro uses a disconnect switch at the pole for farm use, allowing the farmer to shut everything down with out having to call Hydro out. Inside this disconnect there are some very large contacts. They do find their way into the scrap yards.
Hope this helps some of you Newbies on the hunt.
