In the automobile industry, switches are powered actually at 14 VDC and in the future at 42 VDC, and the current level can be from 0.07A to 40A. The aim of this article is to review some studies on the arc duration in this area : effect of current, opening speed and material. The contact materials performances regarding erosion was also investigated. It was found that AgSnO_2, which is claimed as a best compromise at 14 V for all loads, cannot be used at 42 V for tow reasons. It exhibits high erosion and requires a larger contact gap to ensure a successful break.
