Abstract: This disclosure relates to a control assembly, a well pumping system, the system including an electric motor driven pump and a storage tank that receives liquid from the pump. The control assembly includes a mounting plate, a pressure switch that responds to the pressure of the liquid in the tank, the pressure switch being mounted on the plate, a terminal board and a printed circuit board. The terminal board is mounted on the plate adjacent the pressure switch, and power leads are secured to connectors on the pressure switch and on the terminal board. The printed circuit board includes a start winding control switch for the electric motor, and mating quick connect terminals on the terminal and printed circuit boards connect the start winding control switch with the motor. When the motor is a capacitor-start type, a capacitor is connected in the control switch by quick connect terminals, these terminals further serving to support the capacitor on the two boards and the mounting plate.
