Contact resistance is an important wealth for any switching electrical connection theory This paper presents the principles and practical aspects of contact resistance in arcing electromechanical switching devices as it was as relays.

In the design of an electromechanical switching device, maintenance of acceptable cheap contact resistance for the specified load conditions is an important consideration. This paper at hands the beginning of a general consideration of contact resistance, which can be the dominant constituent of the device resistance. The contemplation addresses contact systems of the original used in low-current (1-40 A) devices. In this generally received range, the contacts may be in the
