style="text-indent:25px">行程開關(guān)的應(yīng)用方面很多，很多電器里面都有它的身影。那這么簡(jiǎn)單的開關(guān)能起什么作用呢？它主要是起連鎖保護(hù)的作用。常見的例子莫過于其在洗衣機(jī)和錄音機(jī)（錄像機(jī)）中的應(yīng)用了。在洗衣機(jī)的脫水（甩干）過程中轉(zhuǎn)速很高，如果此時(shí)有人由于疏忽打開洗衣機(jī)的門或蓋后，再把手伸進(jìn)去，很容易對(duì)人造成傷害，為了避免這種事故的發(fā)生，在洗衣機(jī)的門或蓋上裝了個(gè)電接點(diǎn)，一旦有人開啟洗衣機(jī)的門或蓋時(shí)，就自動(dòng)把電機(jī)斷電，甚至還要靠機(jī)械辦法聯(lián)動(dòng)，使門或蓋一打開就立刻“剎車”，強(qiáng)迫轉(zhuǎn)動(dòng)著的部件停下來，免得傷害人身。在錄音機(jī)和錄像機(jī)中，我們常常使用到快進(jìn)或者倒帶，磁帶急速地轉(zhuǎn)動(dòng)，但是當(dāng)?shù)竭_(dá)磁帶的端點(diǎn)時(shí)會(huì)自動(dòng)停下來。在這里行程開關(guān)又一次發(fā)揮了作用，不過這一次不是靠碰撞而是靠磁帶的張力的突然增大引起動(dòng)作的。選擇回訊器種類根據(jù)使用場(chǎng)合及控制對(duì)象。</p><div
