Abstract

1,027,399. Fluid blast switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 22, 1963 [Aug. 27, 1962], No. 32819/62. Addition to 1,018,001. Heading H2B. The circuit breaker of the parent Specification is modified for actuation by the pressure of the fluid insulant. The moving contact rod 18 is mounted upon a piston 2 slidable in a cylinder 3 which is open at one end to the pressurized oil in the chamber 9 and at the other end to the outer atmosphere through a pipe 4.
