明泰電(dian)氣(qi)（蘇(su)州）有限公司是正(zheng)(zheng)(zheng)泰集(ji)團在蘇(su)州地(di)區一家授權的經銷(xiao)(xiao)企業，連續十(shi)年銷(xiao)(xiao)量(liang)居(ju)正(zheng)(zheng)(zheng)泰營(ying)銷(xiao)(xiao)網絡名，公司主要經營(ying)“正(zheng)(zheng)(zheng)泰”牌配電(dian)電(dian)器(qi)(qi)(qi)、控制電(dian)器(qi)(qi)(qi)、終端電(dian)器(qi)(qi)(qi)、電(dian)源電(dian)器(qi)(qi)(qi)、電(dian)力電(dian)子、儀器(qi)(qi)(qi)儀表、建筑電(dian)器(qi)(qi)(qi)、高壓電(dian)器(qi)(qi)(qi)及成套設備。

行程開關的(de)(de)應(ying)(ying)用(yong)方面很多，很多電(dian)器里面都有它的(de)(de)身影。那這么簡單的(de)(de)開關能起(qi)什么作用(yong)呢？它主要是起(qi)連鎖保護(hu)的(de)(de)作用(yong)。常見的(de)(de)例子莫過于其錄(lu)音機(ji)（錄(lu)像機(ji)）中的(de)(de)應(ying)(ying)用(yong)了。

在錄音機和錄像機中，我(wo)們常常使用(yong)到快進或(huo)者(zhe)倒(dao)帶，腳踏開關廠家，磁(ci)帶急(ji)速地(di)轉動(dong)，但是當到達磁(ci)帶的端點時會自(zi)動(dong)停(ting)下來。在這里行程開關又一次(ci)(ci)發揮了作(zuo)用(yong)，不(bu)過這一次(ci)(ci)不(bu)是靠碰撞而是靠磁(ci)帶的張力的突(tu)然增(zeng)大(da)引起動(dong)作(zuo)的。

明泰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)（蘇州(zhou)）有限公(gong)司是正(zheng)泰集(ji)團(tuan)在蘇州(zhou)地(di)區一家授權的(de)經銷企(qi)業，連(lian)續十年銷量(liang)居正(zheng)泰營(ying)(ying)銷網(wang)絡(luo)名(ming)，腳(jiao)踏開關(guan)報價(jia)，公(gong)司主要(yao)經營(ying)(ying)“正(zheng)泰”牌配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)、控制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)、終(zhong)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子、儀器(qi)(qi)儀表、建(jian)筑電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)、高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)及成套設備。

在洗衣(yi)(yi)機的(de)脫水（甩(shuai)干）過程中轉(zhuan)速很(hen)高，如果此時有(you)人由于疏(shu)忽打(da)開(kai)洗衣(yi)(yi)機的(de)門或(huo)(huo)蓋(gai)后，再把(ba)手伸(shen)進去，很(hen)容易(yi)對人造(zao)成傷(shang)害，為了避免(mian)這(zhe)種(zhong)事故的(de)發生(sheng)，在洗衣(yi)(yi)機的(de)門或(huo)(huo)蓋(gai)上(shang)裝了個(ge)電(dian)接(jie)點，一(yi)旦有(you)人開(kai)啟洗衣(yi)(yi)機的(de)門或(huo)(huo)蓋(gai)時，就自動把(ba)電(dian)機斷電(dian)，甚至還(huan)要靠機械辦法聯(lian)動，腳踏開(kai)關供應，使(shi)門或(huo)(huo)蓋(gai)一(yi)打(da)開(kai)就立刻“剎車”，強迫轉(zhuan)動著的(de)部(bu)件停下來，免(mian)得傷(shang)害人身。

限(xian)位(wei)開關(guan)又稱行(xing)(xing)程限(xian)位(wei)開關(guan)，用于控(kong)制(zhi)機械設備(bei)的(de)(de)(de)行(xing)(xing)程及限(xian)位(wei)保護。在(zai)實際生(sheng)產(chan)中，將行(xing)(xing)程限(xian)位(wei)開關(guan)安(an)裝在(zai)預先(xian)安(an)排的(de)(de)(de)位(wei)置(zhi)，當裝于生(sheng)產(chan)機械運(yun)動(dong)部件上的(de)(de)(de)模塊撞(zhuang)擊行(xing)(xing)程開關(guan)時，行(xing)(xing)程限(xian)位(wei)開關(guan)的(de)(de)(de)觸點動(dong)作，實現電路(lu)的(de)(de)(de)切換
