The power switch has a current flow path (7) with two supply terminals (1, 2) and a double breaking contact arrangement. The contact arrangement includes two series connected contact systems (10, 15), in which the current flow path extends in two sections guided parallel to one another. Said sections are formed by an arc (21, 22) during a switching operation. The contact parts (11, 12) of both contact systems are connected to one another and to both supply terminals (1, 2) in such a way that the current in both sections has the same direction. As a result, both arcs (21, 22) attract each other and displacement of the arcs relative to one another is prevented. Both arcs run synchronously into the arc extinction chamber (28, 29) with great reliability and are extinguished therein practically at the same time. The power switch is characterized by high cutout capability.
Circuit breaker having a current path (7) which contains two power connections (1, 2) and a double-interrupting contact arrangement and in which the contact arrangement contains two contact systems (10, 15) which are connected in series in the current path (7) and have a stationary contact (11, 14) and a moving contact (12, 13), in which contact systems (10, 15) the current path has two sections which are routed in parallel with one another and are each formed by a switching arc (21, 22) during a switching process, characterized in that the contacts of the two contact systems are connected to one another and to the two power connections such that the current has the same direction sense in both sections.
