两个交流接触器同时工作，它们的主触点都闭合，必将造成电源短路。因比，为了保证两个接触器不同时工作，在控制电路中，串接了对方的常闭辅助触点RMR和RMF，即把正转接触器RMF的一个常闭辅助触点串接在反转接触器RMR的线圈电路中，而把反转接触器的一个常闭辅助触点串接在正转接触器的线圈电路中。这两个常闭触点称为联锁触点。这样一来, 当按下正转起动按钮SBF时，正转接触器线圈通电，主触点RMF闭合，电动机正转。与此同时，联锁触点断开了反转接触器RMR的线圈电路。因此，即使误按了反转起动按钮SBR，反转接触器也不能动作。在同一时间里两个接触器只允许有一个在工作的控制作用称为互锁作用或联锁作用。

但是在正转过程中要求反转，必须先按停止按钮SB1，让联锁触点RMF闭合后，才能按反转启动按钮使电动机反转，这样一来，带来操作上的不方便。为了解决这个问题，除了利用接触器的动断触点进行电气互锁外，还可以利用复合按钮触点动作的先后顺序不同进行机械互锁。就是这种控制电路的辅助电路(主电路与前相同)。每一个复合按钮都有一副动合触点和一副动断触点，两个启动按钮的动断触点分别与对方的接触器线圈串联。当按下正转启动按钮SBF时，它的动断触点先断开反转接触器的线圈电路；当按下反转启动按钮SBR时，它的动断触点先断开正转接触器的线圈电路。因此,采用这种复合按钮，在改变电动机转向时可以不必先按停止钮，只要按下相应的另一起动按钮即可。如果两种互锁方式同时采用，构成双重互锁，相互制约工作更为可靠。
