Attitude Sensing Electrical Switch
US Patent:
6396012, May 28, 2002
Filed:
Jun 14, 1999
Appl. No.:
09/332750
Inventors:
Rodger E. Bloomfield - Linden MI 48451
International Classification:
H01H 2906
US Classification:
200233, 200152
Abstract:
An attitude sensing electrical switch uses an electrically conductive powder as the switching medium. The powder has a particle size and shape that enables it to flow smoothly into and out of contact with electrical terminals mounted in the switch. Silver, gold, and copper powders with a particle size between one-hundred-forty and three-hundred microns perform effectively.

Filed:
Nov 18, 1974
Appl. No.:
5/524486

International Classification:
B01J 800, F01N 315, F01N 700
US Classification:
