Definitions

  • this embodiment differs from that of FIG. 1 in that the resistance to mercury-splashing is provided by the shape of lower wall 14, rather than by the convex apex of upper wall 13.
  • Lower wall 14 in the present embodiment is provided with a necked-in portion 16, which is so spaced from upper wall 13 as to resist splashing of a large portion of the mercury therebetween but to permit free flow upon tipping of chamber 10 about its vertical axis.
  • Necked-in portion 16 also provides a quick, clean break" of contact between the electrodes upon tipping when the mercury has cleared the hump provided thereby.
  • both electrodes 12 enter chamber 10 through lower wall 14.
  • Tilt-actuable electrical switch means comprising a chamber means defined by spaced inner and outer wall means of generally conical configuration, said wall means being joined at their peripheries, electrically conductive liquid within said chamber means, electrode means terminating within said chamber means, and motion restriction means comprising a convexity of said inner wall means at the apex thereof toward the base thereof, the space between said motion restriction means and said outer wall means being substantially filled by said electrically conductive liquid.
