Contact Lubricants - Electrolube
Contact lubricants are used extensively for connectors. Connectors in early automotive applications were plagued with “fretting corrosion” problems. Although tin and silver plated contacts are more commonly used, gold plated contacts are also apparent in some connector designs. Gold is a soft material and can exaggerate fretting corrosion. ...

Contactor - Wikipedia
A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit, which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. ...
