Abstract
In the process of fixing a metal screen in the housing of a vacuum switch, the screen is plastically deformed radially outwards over an internal supporting edge in the housing. The plastic deformation of the screen is carried out at an edge thereof, in such a way that an outward flanged edge is formed. Thus, the screen is retained on the supporting edge by that flanged edge and a part of the housing with a relatively large diameter. Therefore, the screen has a part with a relatively small diameter which is essentially equal to the internal diameter of the supporting edge of the housing.
