Abstract

1. Insulating nozzle body (1, 2, 9) for an electrical gas blast switch having two matching contact pieces which can be mutually engaged and separated, and one (4) of which shuts off the nozzle when the switch is closed and frees it during its opening movement, and with an insert piece (3, 8) which is resistant to burn-off, characterized in that the insert piece is an insert ring (3, 8) made of graphite, and located in the most constricted region of the nozzle duct (1, 2, 9).
