Abstract:
A vacuum switching device comprising an evacuated envelope including an insulating cylinder, a stationary contact electrode and a movable contact electrode housed within the envelope. The electrodes are adapted to be engaged or disengaged to close or open a circuit in which the device is connected. At least one of the electrodes comprises a coil which, in use, is adapted to generate magnetic fields to control the formation of arcs when the electrodes are disengaged, each electrode having an end face adapted to contact the other electrode when in the engaged condition. At least one of the electrodes has a low resistance electrical path transverse to the axis of the electrode in a region of the end face.
