Abstract (en)

[origin: WO2021023325A1] The present invention relates to an electrical switch (100) for opening a current path (102). The switch (100) has a feed line (108) having an opening point (112) for opening the current path (102). At the opening point (112), a switching element (114) movable at least on one side is arranged in the feed line (108) in order to open and/or close the opening point (112). In a closed position, the switching element (114) has, on a movable side, a point of contact (118) with the feed line (108). The switch (100) also has a return line (110), which is electrically connected to the feed line (108) at an end of the feed line (108). A spaced arrangement of the feed line (108) and the return line (110) substantially antiparallel to each other, at least in the region of the opening point (112), is designed to at least partially compensate, by means of a Lorentz force (124) acting on the switching element (114) from the return line (110), a force which, while the current path (102) is carrying current, acts on the switching element (114) as a result of a local Lorentz force in the feed line (108) and in the switching element (114) and/or as a result of a constriction force (122) in the point of contact (118).
