housing which consists of a cylindrical insulating body 3 composed of glass or ceramic and of two metallic end plates 4 and 5 which seal the end sides of the insulating body 3 in vacuum tight fashion without this vacuum tight housing two separable contact components 1 2 are arranged opposite one another one being secured to a stationary solid current supply pin 6 and the other being secured to a mobile solid current supply pin 7 the current supply pins 6 7 serve to supply the current and to mechanically guide the contact components 1 2 the mobile current supply pin 7 is connected to a metal bellows 8 which hermetically seals the vacuum switch between the mobile current supply pin 7 and the end plate 5 normally a screen 9 is provided in vacuum switches in order to protect the insulating body 3 from the precipitation of metal particles which can evaporate or be torn away from the contact components 1 2 during the disconnection the structure for the two symmetrical contact components 1 2 can be most clearly seen in the enlarged side view of fig2 and the enlarged plan view in fig3 of the contact component 2 the contact component 2 consists of a metallic contact carrier.
