ABSTRACT:
A vacuum switching chamber includes a switching chamber housing having two housing parts. The two housing parts are constructed in the shape of pots or bells and each have a base which encloses an opening through which a respective supporting stalk passes. A stationary contact piece and a moving contact piece are each carried on a respective one of the stalks. The structural size of the vacuum switching chamber is reduced by inwardly drawn bases and furthermore, components and solder foils which would be used in addition to the cylindrical switching chamber housing are rendered unnecessary.
