摘要： The invention relates to a contactor for DC operation, comprising a first contact (21) and a second contact (22), these contacts being in the form of fixed contacts, a third contact (31) and a fourth contact (32), a contact bridge (4) which supports the third and fourth contacts (31, 32), a guide (9) by means of which the contact bridge (4) can be mounted such that it can move along a movement direction, a magnet arrangement (5) for generating electromagnetic force on electric arcs (8) which are produced when the contacts (21, 22, 31, 32) are opened, wherein contact is established between a first pair of contacts, which comprises the first and the third contact (21, 31), and between a second pair of contacts, which comprises the second and the fourth contact (22, 32), in a closed position of the contact bridge (4). The invention is characterized in that the moving contact bridge (4) has at least one cutout (42) which is arranged between the guide (9) and the third contact (31), wherein the at least one cutout (42) is formed in such a way that an opening is provided in the contact bridge (4), it being possible for an arc (8) which is produced at the third contact (31) to pass through said opening in the direction of the movement direction of the contact bridge (4).
