Secondary circuit diagram of single-button start and stopPhysical wiring diagramCircuit diagramWorking Principle:1. Close QF to connect the power supply. Press SB, and the relay KA1 is energized and pulled in. The normally open contact of KA1 is closed, the coil of the AC contactor KM is energized, KM is pulled in and self-locked. The motor operates.2. The normally open contact of KM is closed, and the normally closed contact is disconnected. At this time, the coil of the relay KA2 cannot be ene
