在控(kong)制電路(lu)中(zhong)，經常用到兩(liang)路(lu)或(huo)兩(liang)路(lu)以(yi)上(shang)的電源(yuan)或(huo)負(fu)載(zai)換用的開關電(dian)器---轉換開關(guan)。使(shi)用時(shi)，正(zheng)確(que)連接轉換開關(guan)與(yu)其他(ta)電(dian)器元件(jian)是很(hen)必要的。這裏介(jie)紹(shao)轉(zhuan)換開關(guan)的接法與用途。轉(zhuan)換開關(guan)是(shi)壹種(zhong)可(ke)供(gong)兩(liang)路(lu)或(huo)兩(liang)路(lu)以(yi)上(shang)電(dian)源(yuan)或(huo)負(fu)載(zai)轉換用的開關電(dian)器。轉和星-三(san)角起(qi)動(dong)等(deng)。這(zhe)些部(bu)件(jian)通過(guo)螺(luo)栓緊(jin)固為(wei)壹(yi)個整(zheng)體。轉換開關(guan)又(you)稱組(zu)合(he)開關，與(yu)刀(dao)開(kai)關(guan)的操作不(bu)同，它是(shi)左(zuo)右(you)旋轉的平面操作。

轉(zhuan)換開關(guan)具(ju)有(you)多觸(chu)點(dian)、多位(wei)置、體積(ji)小、性(xing)能可(ke)靠(kao)、操作方(fang)便(bian)、安(an)裝靈(ling)活(huo)等(deng)優(you)點(dian)，多用(yong)於機床(chuang)電(dian)氣控(kong)制線路(lu)中(zhong)電源(yuan)的引(yin)入開(kai)關(guan)，起(qi)著隔(ge)離電(dian)源(yuan)作(zuo)用(yong)，還(hai)可(ke)作(zuo)為(wei)直接控(kong)制小容量(liang)異(yi)步電動(dong)機不頻繁(fan)起(qi)動(dong)和(he)停(ting)止的控(kong)制開關(guan)。轉(zhuan)換開關(guan)同(tong)樣也有(you)單(dan)極(ji)、雙(shuang)極(ji)和(he)三(san)極(ji)。轉(zhuan)換開關(guan)的接觸(chu)系(xi)統(tong)是由數個裝嵌在絕緣殼(ke)體內的靜觸(chu)頭座(zuo)和可(ke)動(dong)支架(jia)中的動觸(chu)頭構成(cheng)。動觸(chu)頭是雙(shuang)斷(duan)點(dian)對接(jie)式的觸(chu)橋，在附有(you)手柄的轉軸上(shang)，隨(sui)轉(zhuan)軸旋(xuan)至不同(tong)位置(zhi)使(shi)電(dian)路(lu)接(jie)通或斷(duan)開。仙童(tong)電(dian)磁閥fairchild平面操作

定(ding)位機構采用滾輪(lun)卡(ka)棘(ji)輪(lun)結構，配(pei)置不同(tong)的限位件(jian)，可(ke)獲得(de)不(bu)同(tong)檔位的開關。在控(kong)制和測(ce)量(liang)系(xi)統(tong)中，采用(yong)轉換開關(guan)可(ke)進(jin)行(xing)電(dian)路(lu)的轉換。例如(ru)電(dian)工設(she)備供(gong)電電源(yuan)的倒換，電動(dong)機的正(zheng)反(fan)轉(zhuan)倒換，測量(liang)回(hui)路(lu)中(zhong)電壓(ya)、電(dian)流(liu)的換相等(deng)等(deng)。轉(zhuan)換開關(guan)是(shi)刀開關(guan)的壹種(zhong)發(fa)展，其區別(bie)是(shi)刀開關(guan)操作時(shi)上(shang)下(xia)平面動(dong)作(zuo),轉換開關(guan)則是(shi)左(zuo)右(you)旋轉平面動(dong)作(zuo),並(bing)且(qie)可(ke)制成多觸(chu)頭、多檔(dang)位的開關。

轉(zhuan)換開關(guan)可(ke)作(zuo)為(wei)電(dian)路(lu)控(kong)制開關(guan)、測(ce)試(shi)設(she)備開(kai)關、電動(dong)機控(kong)制開關(guan)和(he)主(zhu)令(ling)控(kong)制開關(guan)，及(ji)電焊(han)機用轉換開關(guan)等(deng)。轉(zhuan)換開關(guan)壹(yi)般應用(yong)於交流50HZ，電(dian)壓(ya)至380V及以(yi)下，直流電壓(ya)220V及(ji)以(yi)下電(dian)路(lu)中(zhong)轉換電氣(qi)控(kong)制線路(lu)和(he)電氣測(ce)量(liang)儀表。例(li)如(ru)常用LW5/YH2/2型轉(zhuan)換開關(guan)常用於轉(zhuan)換測量(liang)三(san)相電(dian)壓(ya)使(shi)用(yong)。組合(he)開關適(shi)用(yong)於(yu)交流50HZ，電(dian)壓(ya)至380V及以(yi)下，直流電壓(ya)220V及(ji)以(yi)下，作(zuo)手動(dong)不(bu)頻繁(fan)接(jie)通(tong)或(huo)分(fen)斷(duan)電路(lu)，換接電(dian)源(yuan)或(huo)負(fu)載(zai)，可(ke)承(cheng)載(zai)電(dian)流(liu)壹(yi)般較(jiao)大(da)。
