Abstract

1,126,083. Vacuum switches. A. REYROLLE & CO. Ltd. 24 Aug., 1967 [7 June, 1966], No. 25263/66. Heading H1N. The metal condensation shield 11 inside the evacuated envelope 13 of a vacuum switch is corrugated longitudinally, 12, to increase its surface area. The shield may be a cylinder as shown, with parallel corrugations or may be barrel-shaped or alternatively it may be a solid body having a barrel-shaped corrugated internal surface. A further disc-shaped shield 21 protects a bellows seal 19.
