Vacuum switch chamber with movable and fixed contact tip - has two outer cylinder parts of insulation material with flanged end of inner screening soldered in between

摘要

The vacuum switch chamber is formed by a pair of coupled cylindrical parts [10,11] of insulation material. Within the cylinder is a metal screening formed by two elements [12,13] that have an overlapping region [16] with the larger one having a formed flange [17] that is soldered between the ends of the chamber parts. The ends of the screening elements have cone shaped sections [14,15].
