Abstract

An electromechanical switching device (10) for breaking an electric current, the switching device (10) comprising a stationary main contact (12); a movable main contact (14); a stationary arcing contact (16); a movable arcing contact (18), the stationary arcing contact (16) and the movable arcing contact (18) being arranged in parallel with the stationary main contact (12) and the movable main contact (14); an actuating arrangement (22) configured to move the movable main contact (14) and the movable arcing contact (18); and a magnetic member (30) arranged to generate a magnetic holding force in response to an electric current flow through the movable arcing contact (18) when the movable arcing contact (18) is in the closed position, the magnetic holding force acting on the movable arcing contact (18) in a direction against the stationary arcing contact (16).
