Abstract

An electrical switching device has a first interrupter unit for interrupting and connecting an electrical line, in particular an air-insulated grounding switch. A method for switching an air-insulated grounding switch assures that no arc owing to a voltage flashover is produced on the air-insulated grounding switch. A second interrupter unit, which is connected in parallel with the first interrupter unit, can be switched such that resultant striking of an arc during switching only takes place in the second interrupter unit.
