Definitions

  • the other or movable contact is arranged on the inner end of a composite stem or operating shaft, extending downwardly (in FIG. 1) through the lower portion of the envelope and a bellows seal; and through a vertical replaceable bearing structure to the outside of the envelope, where it may be connected to a suitable operator.
  • the inner end of the composite stem is a copper head block conductively connected to the remote terminal by a plurality of conductive flexible straps.
  • the next section of the composite stem is a dielectric rod, mechanically connecting the copper head block to a steel shaft sealed by the bellows in an external and removable bearing structure mounted on the lower end wall of the envelope.
  • my invented structure herein explained as a switch, comprises a vacuumized envelope 6, hermetically closed at one end by a copper plate 7, forming one of two external terminals of the switch, and at its opposite end by a steel plate 8, conveniently serving as a mounting base for the envelope.
  • the side walls of the envelope are two axially aligned cylindrical glass shells 9 and 10 which may be the same in section or of ditlerent section as shown.
  • the shells are hermetically sealed to the end plates by the conventional circular sealing flanges 12 and 13.
  • the two shells are hermetically united by a continuous copper band com-prised of twin sealing flanges 14 and 16, oppositely extending and integrally united by a. centrally grooved circular copper band 17 between them.
  • a two-piece ring 18 brazed in the groove provides a terminal ring midway between the two end plates.
  • a combination according to claim 1 in which the radially flexible conductive means connecting the head to the sealing band comprises a plurality of thin corrugated metallic bands arranged circumferentially about the head to provide an effective spatter shield.
