Abstract
The present invention provides a fluid level sensing switch for use with a device having a fluid reservoir. The switch is float activated and closes a circuit so as to change an operating parameter in the event that the volume of fluid in the reservoir falls below a predetermined level. Once the volume of fluid is restored to a predetermined safe level, the switch automatically resets to an open position to permit normal operation of device.
