In reality, sometimes it needs to manually jog to operate the motor for long operation. The circuit shown in Figure is designed to address this issue. When the start button ST is pressed, motor M is normal startup, and the circuit utilizes its normally open auxiliary contact to lock it by itself, then the motor M can make long-term operation. Pressing STP can stop motor M. If you press the button SB, motor M starts. Because pressing SB normally open contact also disconnects normally closed contacts, and SB is loosen, KM loses electric, then motor M stops, this mode is called jog .
