Abstract
A switching device includes a contact system having a movable contact to be moved along a movement direction, a stationary contact and an improved arc quenching device with a configuration for generating a magnetic field formed in a plane perpendicular to the movement direction and an electrode configuration having a first electrode conductively connected to the movable contact and a second electrode conductively connected to the stationary contact. The first electrode and the second electrode are disposed in such a way that an electric field can be generated between the first electrode and the second electrode perpendicularly to the direction of movement and perpendicularly to the magnetic field.
