The utility model provides an interelectrode electric current transfer switch, including initiative branch road, driven branch road and full-bridge submodule piece, the branch road of taking the initiative also includes the last bridge arm and lower bridge arm of establishing ties including the last bridge arm and the lower bridge arm of establishing ties, driven branch road, be connected with the first ploe wire between the last bridge arm of last bridge arm and the driven branch road of initiative branch road, be connected with extremely wire of third between the lower bridge arm of initiative branch road and the lower bridge arm of driven branch road, be connected the second ploe wire between two bridge arm tie points of initiative branch road and two the bridge arm tie points of driven branch road. Compared with the prior art, the utility model provides a pair of interelectrode electric current transfer switch, when having reduced the upset of third utmost point wire voltage polarity, direct current's rate of change has also reduced the electric current that interelectrode electric current transfer switch need break off simultaneously.
