Abstract

1410802 Vacuum switches ZAKLADY APARATURY ELEKTRYCZNEJ ELESTER 16 Nov 1972 52914/72 Heading H1N In a vacuum switch the fixed and moving contacts 8, 7, are carried by and connected to respective cup shaped metal members 3, 2, which are arranged mouth to mouth to define an annular gap between their nearest peripheries and which are joined together by a glass or ceramic ring 4 which adheres to the outside of the side walls of the metal members over a total axial distance greater than the said gap between the cup-shaped members.
