...Robert L. Jackson; Santosh Angadi In many devices and applications, electrical contacts are exposed to vibrations, sliding, or rolling conditions and are prone to fretting-based degradation. Thus, lubricants are often employed in such contacts to reduce sliding wear and fretting corrosion. However...

Although this investigation was motivated by MEMS switch contacts, the intent of this analysis is also to aid in the design of electrical contacts in various other types of switches. The dimensionless quantities used allow these results to be used for different materials...
