Abstract :
A measuring system for three dimensional (3D) surface profile of an operating electric contact (switch) was applied to experiments on relationship between contact performance and its phenomena. The system developed by the authors measures a 1 mm diameter surface of an electric contact electrode with 10 μm resolution within 4 seconds. The configuration of the system and results of the experiment are described
