Summary :

AgCdO12wt% contacts mounted on electromagnetic relays are tested in a DC 42 V-8.4 A resistive circuit as make-only contacts and break-only contacts. In this experiment, the arc duration has been measured for each operation and the shape of the transferred pip on each contact has been observed using photograph records taken every 1000 operations. The transferred pip grows markedly at make-only contacts. Furthermore, as a few samples with the long arc duration have the flat hill transferred from the cathode on the anode surface of break-only contacts, we believe that the transferred direction reverses at a certain arc length.
