摘要
A switching device, in particular a power switching device, has two pairs of series-connected switching contacts for interrupting a conducting path and at least one quenching packet, disposed near the pairs of switching contacts, for quenching the arcs occurring when the conducting path opens. The pairs of switching contacts are arranged such that their opening paths are substantially mutually parallel or antiparallel. The pairs of switching contacts are connected in series such that the same current flowing in both arcs flows spatially in the same direction. The quenching packet is disposed in the area between the opening paths.
