Abstract
A current sensing switch for use with a pump that is physically separate from the pump and contains a current sensor for measuring the electrical current flowing to the pump as a method of determining whether the pump is operating in low fluid, dry conditions, or with an impeller that has ceased to rotate. When the current drops below or raises above a predetermined value for a predetermined amount of time, the switch electrically disconnects power to the pump and reconnects it periodically to check whether the state of the pump has changed.
