The power switch has switching points containing arc electrodes (10,20), arranged in a vacuum chamber. A magnetic field generator (80) generates magnetic field effecting in a cutting slit (40), independent of the switching current. The generator is arranged such that the magnetic field is aligned perpendicular to the axis, after the discharge of the switching arc arising during the disconnection of the power switch. The electrodes are movable relative to one another along an axis under the formation of a separation gap. |
