A contact member for electrical switching devices, in particular contactors, having a linear power supply conductor and an arc runner disposed at a distance from the contact face of the linear power supply conductor. The arc runner has a U-shaped design having an unattached end which receives the electric arc. The unattached end is in the same plane as the contact face of the power supply conductor. The U-shaped portions of the arc runner are displaced in parallel and laterally away from the contact face of the linear power supply conductor. The attached end of the U-shaped arc runner is sued to secure the arc runner. For this purpose, a groove is introduced into a block-shaped power supply conductor. A segment, joined to the attached end of the arc runner, is inserted into this groove for securing purposes.
