Just shown in the figure, the left circuit is the primary circuit (main circuit) and the right circuit is the secondary circuit (control circuit, the operating circuit). FT is the thermal relay. When STF is pressed, the AC contactor KMF pulls to drive the main contacts of KMF to take action. Then the motor rotates forward (forward). When STF is released, the motor stops working. It is called forward jog . When STR is pressed, KMR pulls to drive the main contact of KlMR to take action. Then the motor rotates in reverse (reverse). When the STR is released, the motor stops rotating. So it is called reverse jog.
