摘要
The subject matter of the present invention is a change in voltage load release switch (20, 30) for contact lines of a web current supply networkwith a first main contact (9) and a movable second main contact (6), wherein the movable second main contact (6) for the production of an air gap of the first main contact (9) can be moved away, andwith a vacuum switching device (25), which, by means of an actuating arrangement (22, 23) in dependence on the position of the movable second main contact (6) before the separation of the main contacts (6, 9) - not turned on and after the closing of the main contacts (6, 9) can be switched on,characterized in thatthe vacuum switching device (25) directly in the current path of the main contacts (6, 9) is arranged.Furthermore, a method for the operation of a change in voltage load switch the subject matter of the invention of the partition.
