Cool. It amazes me the level of engineering that must go into things like those pins and the button contacts to make them reliable and durable for a long period of use in a variety of environments and abusive situations.
They can't even build a new rv that won't leak water for $100k but these go through *** for the tiny fee of 1k
Gold is included in a group of metals referred to as "noble" due to their resistance to corrosion. The resistance to corrosion is the reason for plating electrical contacts in gold -- the electrical conductivity of copper is actually higher than that of gold, so by plating the copper wires you're actually reducing the conductivity.
