Abstract

1,083,874. Glas-blast switches. ETABLISSEMENTS MERLIN & GERIN SOC. ANON. March 16, 1965 [March 26, 1964], No. 11052/65. Heading H2B. A gas-blast switch comprises a tubular gasevolving chamber 21, a stationary contact 11 outside the chamber, a tubular or cylindrical contact 15 movable axially within the chamber and co-operating with the stationary contact, and an insulating plug-like member 18 moving with the movable contact during the first part of its movement until the member engages a seating and closes the end of the chamber adjacent the stationary contact. The movable contact may have a tip 16 of gas-evolving insulating material and the plug-like member 18 which may be gas-evolving, may be supported by either the moving or the stationary contact, a spring 19 biasing the member 18 towards the contact 15. The stationary contact 11 and the chamber 21 may be housed within a two-part flame-proof bushing 24, 25 provided with vents 30.
