Abstract
An electrical interruption switch having a casing which surrounds a contact unit which defines the path of the current through the interruption switch, and having a propellant charge having a gas-generating activatable material. The contact unit has a first and a second connection contacts, an upsetting region, a separation region and a sabot. An extinguishing agent is provided in such a way that the motion of the sabot and/or the upsetting of the upsetting region reduces the volume for receiving the extinguishing agent in such a way that the extinguishing agent is injected through at least one discharge channel that connects the volume for receiving the extinguishing agent to the chamber in which the separation region is located, in order to extinguish or to prevent the formation of an electric arc between the ends of the separation region.
