Abstract

A switch, in particular a grounding switch, is for quickly establishing a ground connection and for extinguishing an arc fault for a switching system. The grounding switch includes at least one fixed contact having a first cable feed, a moving contact, a contact guide having a second cable feed, and a mechanical energy store. In the opened state, an insulating distance between the fixed contact and the moving contact, is filled with insulation liquid, at least in part. The switch further includes a triggering device and a locking mechanism.
