Electric interruption switch comprising reactive coating in the reaction chamber

An interruption switch for interrupting high currents at high voltages, the interruption switch comprising:

• a casing, which surrounds a contact unit defining a current path through the interruption switch, the contact unit comprising a first connection contact, a second connection contact and a separation region,
• wherein the contact unit is formed such that a current is supplied to the contact unit via the first connection contact and discharged therefrom via the second connection contact, or vice versa,
• wherein the separation region is formed such that, when separated, the current path between the first connection contact and the second connection contact is interrupted,
• wherein the separation region is arranged inside a reaction chamber;
• and
• a coating with a reactive material present in the reaction chamber, wherein the reactive material is configured to, under influence of an electric arc, attenuate or extinguish the electric arc,
• wherein the reaction chamber is filled with an extinguishing agent which is a liquid medium;
• and,
• wherein the coating is substantially free of carbon-containing materials.
