Why are some Electrical Contacts Gold Plated?
Gold is really expensive. Why then would anyone bother to plate silver contacts with gold? Does it have some unique electrical characteristics that make it useful? Electrical Contacts Gold Plated provide reliable switching when the wetting current is low, because there is no oxide to breach for electrical contact to occur. Ex: a pushbutton switch used to signal a microcontroller digital input has a pullup resistor sized to flow 50 uA when the switch is closed. A switch without gold plating might not be reliable.
Electrical Contacts Gold Plated have several really unique properties that allow for their frequent use:
1-No corrosion at all, produces no patina;
2-Gold Plated Contacts can be touched with bare hands;
3-Reliable in humid environments (household, automotive, marine);
4-Gold is the least likely metal to oxidize. From this table, it can be shown that Gold's electro-potential value is -1.1, meaning it should not oxidize at all, even in water.this is the primary reason that some electrical contacts are gold plated;
5-Gold is an extremely conductive material, one of the best known;
6-Gold Plating Copper Rivet is very malleable, it is very easy to get a thin sheet of it;
