A pump control switch for controlling the operation of a pump, where the pump switch includes a pressure activated switch and a run capacitor located in a single housing. The pressure switch is attached by a pipe fitting to be in fluid communication with the water line that feeds into a storage tank, to sense the water system pressure. The water system pressure sensed by the switch moves the electrical contacts in the switch between their open and closed positions. The pressure switch is disposed to operably electrically interconnect a power source, the run capacitor, and the pump motor.
