Switch for direct current operation with at least one switching chamber

摘要

The switch has a switching chamber (41a) whose switching pieces (10a, 10b) are respectively provided with first contact regions (11) and second contact regions (31) for establishing an electrically conductive connection with the respective first contact regions and for separating from the respective first contact regions. An electrically conductive bridge contact (30) is movable by a movable switching bridge (35). Plate-like magnets (51a, 51b) i.e. permanent magnets, generates a magnetic field. An additional magnet (51c) is arranged on the switching bridge to influence the magnetic field.
