Abstract
The float-operated pump switch provides float-operated pump switching for automatically maintaining the water level in a water tank supplied by a reservoir. The switch operates to start pumping water when the level in the upper tank is one-quarter of the volume of the tank, and continues pumping until the tank is full, thereby providing a hysteresis and reducing the number of times the pump needs to be operated.
