明泰(tai)(tai)電(dian)氣（蘇州）有限公(gong)司是(shi)正泰(tai)(tai)集(ji)團在蘇州地(di)區一家授權的(de)經銷企業，連續十年(nian)銷量居正泰(tai)(tai)營銷網絡名(ming)，公(gong)司主要經營“正泰(tai)(tai)”牌(pai)配電(dian)電(dian)器(qi)、控制電(dian)器(qi)、終端(duan)電(dian)器(qi)、電(dian)源電(dian)器(qi)、電(dian)力(li)電(dian)子、儀(yi)(yi)器(qi)儀(yi)(yi)表、建筑電(dian)器(qi)、高壓(ya)電(dian)器(qi)及成套設備(bei)。

行(xing)程開關主要用(yong)于將(jiang)機械位移轉變成電(dian)信號，使(shi)電(dian)動(dong)機的運行(xing)狀(zhuang)態得(de)以改變，從而控(kong)制(zhi)機械動(dong)作或用(yong)作程序控(kong)制(zhi)。

行程開關真正(zheng)的(de)用武(wu)之地是(shi)在工業上，在那(nei)里它(ta)與其它(ta)設備配合，組(zu)成更復雜(za)的(de)自動化設備。

機(ji)床上有很多這樣(yang)的(de)行(xing)程(cheng)開(kai)關，用它控(kong)制工件運動(dong)(dong)(dong)或自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)進刀的(de)行(xing)程(cheng)，限(xian)(xian)位(wei)開(kai)關供(gong)應商(shang)，避免發生碰(peng)撞事(shi)故。有時利(li)用行(xing)程(cheng)開(kai)關使被控(kong)物體在規定(ding)的(de)兩個(ge)位(wei)置之(zhi)間自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)換(huan)向，限(xian)(xian)位(wei)開(kai)關價格，從而得到(dao)不(bu)斷(duan)的(de)往(wang)復運動(dong)(dong)(dong)。比如自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)運料的(de)小(xiao)車(che)到(dao)達終點碰(peng)著行(xing)程(cheng)開(kai)關，接(jie)(jie)通了翻車(che)機(ji)構(gou)，就(jiu)把車(che)里的(de)物料翻倒出來，并且退回到(dao)起(qi)點。到(dao)達起(qi)點之(zhi)后又(you)碰(peng)著起(qi)點的(de)行(xing)程(cheng)開(kai)關，把裝(zhuang)料機(ji)構(gou)的(de)電路接(jie)(jie)通，開(kai)始自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)裝(zhuang)車(che)。總(zong)是這樣(yang)下去，就(jiu)成(cheng)了一套自(zi)(zi)(zi)(zi)動(dong)(dong)(dong)生產線(xian)，限(xian)(xian)位(wei)開(kai)關廠家，用不(bu)著人(ren)管，日以繼夜地工作，淮(huai)安限(xian)(xian)位(wei)開(kai)關，節省了人(ren)的(de)體力勞動(dong)(dong)(dong)。

明(ming)泰電(dian)氣（蘇州）有限公司(si)是正(zheng)泰集團(tuan)在蘇州地區一家授(shou)權的經(jing)銷(xiao)企業(ye)，連續十年銷(xiao)量居(ju)正(zheng)泰營銷(xiao)網(wang)絡名，公司(si)主要經(jing)營“正(zheng)泰”牌配電(dian)電(dian)器(qi)(qi)、控制電(dian)器(qi)(qi)、終端電(dian)器(qi)(qi)、電(dian)源(yuan)電(dian)器(qi)(qi)、電(dian)力(li)電(dian)子、儀器(qi)(qi)儀表、建(jian)筑電(dian)器(qi)(qi)、高壓電(dian)器(qi)(qi)及成套設備(bei)。

限位開(kai)(kai)關(guan)，指(zhi)為保護內置(zhi)微動開(kai)(kai)關(guan)免受(shou)外力、水、油、氣體和塵埃等的(de)(de)損害，而(er)組(zu)裝在外殼(ke)內的(de)(de)開(kai)(kai)關(guan)，尤其(qi)適用于對機械強度和環境適應 性(xing)有特殊(shu)要求的(de)(de)地方。　形(xing)狀大(da)致(zhi)分為橫向(xiang)型(xing)(xing)、豎向(xiang)型(xing)(xing)和復合型(xing)(xing)。下圖(tu)表示典型(xing)(xing)的(de)(de)豎向(xiang)型(xing)(xing)限位開(kai)(kai)關(guan)的(de)(de)構造。限位開(kai)(kai)關(guan)大(da)致(zhi)上是由(you)五個構成要素組(zu)成的(de)(de)。

斷火限(xian)(xian)位(wei)(wei)開(kai)關(guan)(guan)(guan)(guan)(guan)又稱行(xing)程限(xian)(xian)位(wei)(wei)開(kai)關(guan)(guan)(guan)(guan)(guan)，用(yong)于控制(zhi)機械設備(bei)的(de)(de)行(xing)程及限(xian)(xian)位(wei)(wei)保(bao)護(hu)。在(zai)(zai)實(shi)(shi)際(ji)生(sheng)產中(zhong)，將行(xing)程限(xian)(xian)位(wei)(wei)開(kai)關(guan)(guan)(guan)(guan)(guan)安裝在(zai)(zai)預先安排(pai)的(de)(de)位(wei)(wei)置，當裝于生(sheng)產機械運(yun)動(dong)部件(jian)上(shang)的(de)(de)模塊撞擊行(xing)程開(kai)關(guan)(guan)(guan)(guan)(guan)時，行(xing)程限(xian)(xian)位(wei)(wei)開(kai)關(guan)(guan)(guan)(guan)(guan)的(de)(de)觸(chu)點動(dong)作，實(shi)(shi)現電(dian)路(lu)的(de)(de)切換。因此，斷火限(xian)(xian)位(wei)(wei)開(kai)關(guan)(guan)(guan)(guan)(guan)是一種根(gen)據運(yun)動(dong)部件(jian)的(de)(de)行(xing)程位(wei)(wei)置而(er)切換電(dian)路(lu)的(de)(de)電(dian)器，它的(de)(de)作用(yong)原理與按鈕類似。限(xian)(xian)位(wei)(wei)開(kai)關(guan)(guan)(guan)(guan)(guan)廣泛(fan)用(yong)于各類機床和(he)起重機械，用(yong)以控制(zhi)其行(xing)程、進行(xing)終(zhong)端限(xian)(xian)位(wei)(wei)保(bao)護(hu)。在(zai)(zai)電(dian)梯的(de)(de)控制(zhi)電(dian)路(lu)中(zhong)，還利(li)用(yong)行(xing)程限(xian)(xian)位(wei)(wei)開(kai)關(guan)(guan)(guan)(guan)(guan)來控制(zhi)開(kai)關(guan)(guan)(guan)(guan)(guan)轎門的(de)(de)速(su)度、自動(dong)開(kai)關(guan)(guan)(guan)(guan)(guan)門的(de)(de)限(xian)(xian)位(wei)(wei)，轎廂的(de)(de)上(shang)、下限(xian)(xian)位(wei)(wei)保(bao)護(hu)。
