A breast pump set for expressing human breastmilk comprises a breastshield (1) to be placed on the female breast with a coupling part (12) for connection to a milk collection container (2), and an electrically driven suction pump (4, 4′). The breastshield (1) is provided with an actuator (5) for actuating the suction pump. The inventive breast pump seat allows easy handling of the suction pump and eliminates the need for the mother to have a hand free for handling.
