Electrical Contact Lubricants

Lubricants designed for electrical switch applications must protect components from wear and corrosion while providing protection against external elements such as dust, humidity, moisture, periods of non-use and wide variations in temperatures. Electrical lubricants should be chosen dependent on contact design (sliding, make and break, slip ring, roller, knife blade, etc.), contact forces, switching amperage requirements and compatibility with plastics, elastomers and metals. Low current switching with low contact forces may require a lubricant with different chemical and physical properties compared to switching high current with high contact forces.
