In this paper, a Micro-Step-Separating System is realized for investigating phenomena of initial state of separating contacts. This system can control the contact separation in a discrete way with about 0.5 µm step. By using this system, we observed a relationship between contact voltage and contact separation gap. Ag contacts were observed. The observation showed that the contact voltage rose up and then fell down to the stable voltage at each step separation. From this observation, we expect to elucidate the contact bridge phenomena with more sophisticated way because we can approach them under the thermal equilibrium condition.
