Abstract: The investigation of electrical low power switching contacts, including dry-circuit, is characterized as a highly interdisciplinary research field. The knowledge of plasma physics, the influence of kinetics on contact phenomena, material science and metallurgy, as well as thermal aspects and tribology, is demanded. The methods usually used at the Austrian Center of Competence for Tribology are e.g. defined contact make and break along two-independent axis using model switches, high-resolution measurement of displacement and electrical values, including the detection of arcs, contact force measurement in the kHz and cN range (one-axis and two-axis systems), on-line optical investigations (especially time lapse movie systems), state of the art 3D surface topography measurement of eroded contact surfaces, and (electron-) microscopical evaluation of metallographic cross sections. Some aspects of this methodology are presented in this paper. [Copyright &y& Elsevier]
