ABSTRACT:
A liquid level sensing device utilizing a conductive hollow sphere buoyed by the liquid and guided vertically within a metal tube. An elongated resistance card is mounted in the tube adjacent the sphere to permit the sphere to slide along its surface as the liquid level changes thereby electrically connecting a portion of the resistance card to the metal housing through the conductive sphere. The resistance card is mounted so as to be flexed from its normal flat configuration with the flexed configuration producing a light force on the sphere to maintain good electrical contact therewith and between the sphere and the housing but insufficient to deter the sphere from following liquid level changes.
