A fluid-level sensing device that uses the interaction of a first magnet
attached to the distal end of an external micro switch arm and a second
magnet positioned within the distal end of a pivoting float body to close
a circuit within the micro switch and create a shut-off signal to stop
fluid production. A single housing holds the micro switch and float body,
wherein magnetic forces acting through the housing wall between them and
other magnet-positioning materials that separate the two magnets cause
signal production. After float body deployment, manual reset of the float
body is accomplished via its lever-like distal end. The main body of the
micro switch, which it is snap-fit into a fixed position within the upper
housing chamber for use, is entirely encapsulated in waterproof material
to protect it from corrosion. Alternative ways for quick mounting of the
housing to a fluid-collecting pan are contemplated.
