開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)是指一(yi)個可以使(shi)電(dian)(dian)路(lu)(lu)開(kai)(kai)(kai)路(lu)(lu)、使(shi)電(dian)(dian)流(liu)(liu)中(zhong)(zhong)斷或(huo)使(shi)其(qi)(qi)流(liu)(liu)到其(qi)(qi)他電(dian)(dian)路(lu)(lu)的電(dian)(dian)子(zi)元(yuan)件。最(zui)常見的開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)是讓人操作機器裝置或(huo)下達命令的操作開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)，其(qi)(qi)中(zhong)(zhong)有(you)一(yi)個或(huo)數個電(dian)(dian)子(zi)接(jie)(jie)點(dian)(dian)(dian)。接(jie)(jie)點(dian)(dian)(dian)的「閉(bi)合」（closed）表示電(dian)(dian)子(zi)接(jie)(jie)點(dian)(dian)(dian)導通，允許(xu)(xu)電(dian)(dian)流(liu)(liu)流(liu)(liu)過；開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)的「開(kai)(kai)(kai)路(lu)(lu)」（open）表示電(dian)(dian)子(zi)接(jie)(jie)點(dian)(dian)(dian)不導通形成開(kai)(kai)(kai)路(lu)(lu)，不允許(xu)(xu)電(dian)(dian)流(liu)(liu)流(liu)(liu)過。 中(zhong)(zhong)國星坤(kun)開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)分(fen)為(wei)：輕觸開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)、撥動開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)、按鍵開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)、微(wei)動開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)、檢(jian)測開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)、多(duo)功能開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)、帶燈開(kai)(kai)(kai)關(guan)(guan)(guan)(guan)(guan)(guan)。

插(cha)座(zuo)(zuo)(zuo)(zuo)也常稱為電(dian)(dian)源插(cha)座(zuo)(zuo)(zuo)(zuo)，音(yin)(yin)頻視(shi)頻插(cha)座(zuo)(zuo)(zuo)(zuo)。插(cha)座(zuo)(zuo)(zuo)(zuo)是指有(you)一(yi)個(ge)或一(yi)個(ge)以(yi)上電(dian)(dian)路接(jie)線可插(cha)入(ru)的座(zuo)(zuo)(zuo)(zuo)，通(tong)(tong)過它可插(cha)入(ru)各種(zhong)接(jie)線。這(zhe)樣便于與(yu)(yu)其他電(dian)(dian)路接(jie)通(tong)(tong)。通(tong)(tong)過線路與(yu)(yu)銅(tong)件(jian)之(zhi)間的連接(jie)與(yu)(yu)斷(duan)開，來達(da)到(dao)最(zui)終達(da)到(dao)該(gai)部分(fen)電(dian)(dian)路的接(jie)通(tong)(tong)與(yu)(yu)斷(duan)開。中國星坤插(cha)座(zuo)(zuo)(zuo)(zuo)系列分(fen)為：音(yin)(yin)頻耳(er)機插(cha)座(zuo)(zuo)(zuo)(zuo)、DC直流電(dian)(dian)源插(cha)座(zuo)(zuo)(zuo)(zuo)。
