Abstract
THE passage of electricity across the opposed A faces of metallic contacts in a current make-and-break circuit involves most of the fundamental mechanisms of electron emission from conductors and semi-conductors and of transport through gases. It is for this reason that a book which gives a comprehensive treatment of the subject is likely to be of interest to the physicist as well as to the electrical engineer and metallurgist concerned with the development of contacts for circuit-breakers, microphones, lind current-collectors. The questions involved are not entirely electrical, for, in addition to problems of powder metallurgy, there are also those of friction, wear, and lubrication; in fact, the study of electrical contacts has led to important conclusions in the theory of friction.
