按下第二台电动机停止按钮X3，Y1线圈失电，第二台电动机停止，同时T0得电延时10s
后T0常闭接点断开，M0失电，M0常开接点断开，M1和T1失电，此时再按下停止按钮X1才能使Y0失电，停止第一台电动机M1.
梯形图22-2（b）：启动时按下启动按钮X0，Y0和T0线圈得电自锁，接触器KM1得电，第一台电动机M1先启动，T0延时10s后接点闭合，为Y1得电，第二台电动机启动做好准备。 按下启动按钮X2，Y1得电自锁，第二台电动机M2启动，Y1常开接点闭合，接通特殊定时器，M0相当于一个断电延时定时器，所以M0常开接点立刻闭合，使第一台电动机停止按钮，X1不起作用。
按下第二台电动机停止按钮X3，Y1线圈失电，第二台电动机停止，同时特殊定时器失电，M0常开接点仍然闭合，T1延时10s后M0失电，M0常开接点断开，此时再按下停止按钮X1才能使Y0失电，停止第一台电动机M1。
