Electrical Contact Design Theory

The engineer or designer who wants to develop or select electrical contact systems must first have a good understanding  of general contact theory. This knowledge must include a grasp of the nature of electrical contact surfaces, the cause and prediction of contact resistance, the effect of thin surface films, and the various thermal and arc phenomena that can occur in contact systems. These underlying principles will influence the performance of all contact systems, so their importance must  not be underestimated.

Properties of Materials

Material properties enter even into the most basic engineering design considerations.  Such factors as hardness, elastic modulus, resistivity, high temperature performance, and other variables will make the difference between a good design or a design that will not meet the application requirements.  Many mechanical and electrical properties will be discussed in detail in the sections below.
