Abstract (en)
[origin: WO2005034162A1] Disclosed is a power switch comprising a current path, in addition to at least one moving contact and at least one fixed contact. The current path is guided between the moving contact and the fixed contact in the form of a narrow loop. A dynamic contact closing force and a dynamic contact opening force are produced from a flowing electric current in order to improve current load capacity. As a result, the magnetic force on the moving contact can be altered from small flows to a very high flows. Advantages during transition from operation in normal rating to short-circuit operation are produced. In order to produce said dynamic forces, ferromagnetic parts (20, 30; 21, 22; 25, 26, 28, 29) are dimensioned in a suitable manner and are associated with the allocated device of the switching bridge (4) provided with moving contacts (5a, 5b).
