兩個(gè)交流接觸器同時(shí)工作，它們的主觸點(diǎn)都閉合，必將造成電源短路。因比，為了保證兩個(gè)接觸器不同時(shí)工作，在控制電路中，串接了對(duì)方的常閉輔助觸點(diǎn)RMR和RMF，即把正轉(zhuǎn)接觸器RMF的一個(gè)常閉輔助觸點(diǎn)串接在反轉(zhuǎn)接觸器RMR的線圈電路中，而把反轉(zhuǎn)接觸器的一個(gè)常閉輔助觸點(diǎn)串接在正轉(zhuǎn)接觸器的線圈電路中。這兩個(gè)常閉觸點(diǎn)稱為聯(lián)鎖觸點(diǎn)。這樣一來(lái), 當(dāng)按下正轉(zhuǎn)起動(dòng)按鈕SBF時(shí)，正轉(zhuǎn)接觸器線圈通電，主觸點(diǎn)RMF閉合，電動(dòng)機(jī)正轉(zhuǎn)。與此同時(shí)，聯(lián)鎖觸點(diǎn)斷開(kāi)了反轉(zhuǎn)接觸器RMR的線圈電路。因此，即使誤按了反轉(zhuǎn)起動(dòng)按鈕SBR，反轉(zhuǎn)接觸器也不能動(dòng)作。在同一時(shí)間里兩個(gè)接觸器只允許有一個(gè)在工作的控制作用稱為互鎖作用或聯(lián)鎖作用。

但是在正轉(zhuǎn)過(guò)程中要求反轉(zhuǎn)，必須先按停止按鈕SB1，讓聯(lián)鎖觸點(diǎn)RMF閉合后，才能按反轉(zhuǎn)啟動(dòng)按鈕使電動(dòng)機(jī)反轉(zhuǎn)，這樣一來(lái)，帶來(lái)操作上的不方便。為了解決這個(gè)問(wèn)題，除了利用接觸器的動(dòng)斷觸點(diǎn)進(jìn)行電氣互鎖外，還可以利用復(fù)合按鈕觸點(diǎn)動(dòng)作的先后順序不同進(jìn)行機(jī)械互鎖。就是這種控制電路的輔助電路(主電路與前相同)。每一個(gè)復(fù)合按鈕都有一副動(dòng)合觸點(diǎn)和一副動(dòng)斷觸點(diǎn)，兩個(gè)啟動(dòng)按鈕的動(dòng)斷觸點(diǎn)分別與對(duì)方的接觸器線圈串聯(lián)。當(dāng)按下正轉(zhuǎn)啟動(dòng)按鈕SBF時(shí)，它的動(dòng)斷觸點(diǎn)先斷開(kāi)反轉(zhuǎn)接觸器的線圈電路；當(dāng)按下反轉(zhuǎn)啟動(dòng)按鈕SBR時(shí)，它的動(dòng)斷觸點(diǎn)先斷開(kāi)正轉(zhuǎn)接觸器的線圈電路。因此,采用這種復(fù)合按鈕，在改變電動(dòng)機(jī)轉(zhuǎn)向時(shí)可以不必先按停止鈕，只要按下相應(yīng)的另一起動(dòng)按鈕即可。如果兩種互鎖方式同時(shí)采用，構(gòu)成雙重互鎖，相互制約工作更為可靠。
