A new vacuum switching chamber is intended for power breakers in the low-voltage range and is distinguished by a compact form with a small physical height and a high switching capacity. Its enclosure includes a plate-like power current connection, a cylindrical wall part which surrounds flat spiral contacts, an annular insulator and a membrane disk with a centrally arranged power current supply bolt.

Vacuum interrupter chamber with ring-shaped insulator

A vacuum interrupter with a tubular insulator, to dielectrically optimize the fixing of a vapor shield which is provided at an encircling step of the ceramic insulator. A holding ring is assigned to the vapor shield and has a cylindrical region, which is supported on the step, and an inwardly projecting collar, one end of the vapor shield being flanged onto the collar.

Vacuum interrupter with a vapor shield

A vacuum tube including a getter apparatus is provided. The getter apparatus includes a sheet-like support with an applied getter layer which is used to maintain vacuum in the vacuum tube during operation. The support has the shape of a strip, and is positioned in a groove of a shield or a contact pin of the vacuum tube. The support is immobilized using impressions of the groove rim.
