An arc runner substantially surrounding the contacts aide in extinguishing the arc created upon separation of the contacts. The overhanging plate of the arc runner has stoppers which engage the side plates thereby preventing the overhanging plate from bending inward and decreasing the effectiveness of the arc runner. The arc runner is also provided with lead parts to separate the arc and purge holes for passing the hot gasses generated.
