A pump overload control assembly is for use with an electric motor driven pump in a water pumping system. The assembly includes a pump overload control device coupled to a fluid responsive switch, thereby forming a pump overload control circuit that interrupts the current flow to the motor in response to an overload of current flow to the motor. The pump overload control device includes a resettable overload protector and indicator mechanism that visually indicates when an overload has occurred and breaks the current flow through the circuit, for example, in response to heat generated from the overload current flow. The fluid responsive switch opens and closes the circuit in response to the fluid being pumped to an external source, for example, when the fluid pressure level falls below or rises above a predetermined pressure level. The pump overload control device further includes a power light, for indicating when power is being supplied to the pump overload control device and a run light, for indicating when current is flowing to the motor. The pump overload control device is mechanically mounted to and supported by the fluid responsive switch.
