| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Material transfer and erosion caused by arc discharges during operations of mechanical relays and switches is one of critical phenomena that may lead to serious contact failures. Understanding of their characteristics such as influences of load conditions as well as contact materials is one of important issues for realizing better reliability and longer lifetime of relays and switches. In this paper, crater and pip shapes grown on surfaces of Ag and AgSnO2 contacts that were operated to conduct the 50,000 break operations of an inductive DC14V-2A load current are observed with several different measurement techniques, and advantageous and disadvantageous features of the respective techniques are compared with each other. | |
