摘要

Based on the experimental results of the references [1] and [2], i.e., the contact re- sistance increases due to the contaminants formed on contact surface with the operating cycles, the physical model and math model of contact failure on small current contacts under mechanical actions are proposed through deep theoretical analysis in this paper.
