雙(shuang)控(kong)(kong)開(kai)關是(shi)指對(dui)某(mou)個設備進(jin)行兩(liang)(liang)個地(di)方的分別控(kong)(kong)制(zhi)，比(bi)如如果是(shi)照明燈(deng)(deng)，那有在(zai)客廳(ting)進(jin)門(men)控(kong)(kong)制(zhi)客廳(ting)燈(deng)(deng)光(guang)的，你(ni)到(dao)了(le)臥室要(yao)睡覺(jue)的時候再跑去客廳(ting)關燈(deng)(deng)就(jiu)累(lei)了(le)，在(zai)臥室你(ni)可(ke)以(yi)也安一(yi)個開(kai)關對(dui)客廳(ting)燈(deng)(deng)進(jin)行控(kong)(kong)制(zhi)。同樣在(zai)工廠里面(mian)對(dui)某(mou)個電(dian)(dian)機進(jin)行兩(liang)(liang)地(di)控(kong)(kong)制(zhi)都是(shi)很平常的事情，所以(yi)雙(shuang)聯雙(shuang)控(kong)(kong)就(jiu)是(shi)指不地(di)方的兩(liang)(liang)個面(mian)板上(shang)各兩(liang)(liang)個鍵，共控(kong)(kong)制(zhi)兩(liang)(liang)個電(dian)(dian)源達(da)到(dao)在(zai)不同地(di)方可(ke)以(yi)控(kong)(kong)制(zhi)同一(yi)設備。

雙(shuang)(shuang)控(kong)(kong)開關(guan)(guan)因為控(kong)(kong)制面板上開關(guan)(guan)按鈕的不同可以分為單(dan)聯雙(shuang)(shuang)控(kong)(kong)開關(guan)(guan)、雙(shuang)(shuang)聯雙(shuang)(shuang)控(kong)(kong)開關(guan)(guan)、三聯雙(shuang)(shuang)控(kong)(kong)開關(guan)(guan)，按照(zhao)聯數的增加(jia)接線困難也會遞增。

單聯(lian)(lian)雙(shuang)控(kong)開(kai)關(guan)(guan)(guan)(guan)實際上(shang)(shang)就是(shi)兩(liang)個(ge)(ge)(ge)單刀(dao)(dao)雙(shuang)擲開(kai)關(guan)(guan)(guan)(guan)串(chuan)聯(lian)(lian)起來后再(zai)接入(ru)電(dian)(dian)路的(de)開(kai)關(guan)(guan)(guan)(guan)。每個(ge)(ge)(ge)單刀(dao)(dao)雙(shuang)擲開(kai)關(guan)(guan)(guan)(guan)有三個(ge)(ge)(ge)接線端，分別連著兩(liang)個(ge)(ge)(ge)觸點和一個(ge)(ge)(ge)刀(dao)(dao)。雙(shuang)聯(lian)(lian)雙(shuang)控(kong)開(kai)關(guan)(guan)(guan)(guan)的(de)定(ding)義與單聯(lian)(lian)雙(shuang)控(kong)開(kai)關(guan)(guan)(guan)(guan)的(de)定(ding)義差不多，唯(wei)一的(de)區別就是(shi)雙(shuang)聯(lian)(lian)是(shi)2個(ge)(ge)(ge)按(an)鈕的(de)開(kai)關(guan)(guan)(guan)(guan)，單聯(lian)(lian)就只是(shi)一個(ge)(ge)(ge)按(an)鈕的(de)開(kai)關(guan)(guan)(guan)(guan)。那什么(me)是(shi)雙(shuang)聯(lian)(lian)雙(shuang)控(kong)開(kai)關(guan)(guan)(guan)(guan)呢?其實很簡單，就是(shi)指在一個(ge)(ge)(ge)面(mian)板上(shang)(shang)，通過兩(liang)個(ge)(ge)(ge)按(an)鈕來控(kong)制(zhi)兩(liang)個(ge)(ge)(ge)用電(dian)(dian)設備，就是(shi)兩(liang)個(ge)(ge)(ge)開(kai)關(guan)(guan)(guan)(guan)控(kong)制(zhi)這兩(liang)條電(dian)(dian)路。
