限位開(kāi)關(guān)主要由開(kāi)關(guān)元件、接線端子、開(kāi)關(guān)操動(dòng)件、傳動(dòng)部分組成，根據(jù)開(kāi)關(guān)觸頭接通和斷開(kāi)機(jī)械處理，開(kāi)關(guān)元件有下述二類：

緩動(dòng)開(kāi)關(guān)：開(kāi)關(guān)的接通和斷開(kāi)動(dòng)作切換時(shí)間與開(kāi)關(guān)操動(dòng)速度有關(guān)，操動(dòng)速度越快、開(kāi)關(guān)的切換也越快。

速動(dòng)開(kāi)關(guān)：開(kāi)關(guān)的接通和斷開(kāi)的轉(zhuǎn)換時(shí)間與開(kāi)關(guān)和被操動(dòng)的速度無(wú)關(guān)，只要開(kāi)關(guān)操動(dòng)部件被操動(dòng)到一定，開(kāi)關(guān)便發(fā)生通和斷開(kāi)切換，此過(guò)程時(shí)間一般為彈簧跳所需時(shí)間，此時(shí)間極短，為一常數(shù)。
