FIELD: electricity.
SUBSTANCE: switching device comprising a first set (3) of contacts and a second set (4) of contacts movable with respect to the first set (3) of contacts has an insulating nozzle device (12). The insulating nozzle device (12) is supported by a first set (3) of contacts, comprising a first arc interrogation element (15) mounted movably with respect to the insulating nozzle device (12). In this case, the insulating nozzle device (12) comprises a main nozzle (12a) and an auxiliary nozzle (12b), each of which limits the corresponding portion of the nozzle channel.
EFFECT: reduction of loads tested by the structural components of the switching device.
