Abstract

Improvements in electric cut-off switches in a gaseous atmosphere, such as a halogenated gas, this gas being self-compressed when disengaged by movement in a cylinder of a piston that carries the moving contact, the self-compressing gas being directed on the arc in order to extinguish it and the switch being mounted inside a closed chamber, characterized in that the hollow mobile contact tube terminated in a short solid rod that forms the contact itself moves inside an insulating sleeve that extends between the cylinder and the fixed contact that forms a blowing nozzle, the gas compression chamber being in the cylinder, in communication with the atmosphere of the enclosure outside the cylinder and to the insulating sleeve by means of the insufflation nozzle and through the holes provided at each end of the hollow mobile contact tube, opening these holes on the one hand inside the insulating sleeve and on the the other part in the gas compression chamber, this communication being interrupted only in the hooked position and at the beginning of the unhooking by the sealing of the blowing nozzle by the solid rod of the moving contact, while the cylinder is on the side of its bottom that the insulating sleeve is in permanent communication with the aforementioned atmosphere of the enclosure through openings arranged in the wall of the cylinder.
