主要分類 按主觸(chu)點連接回(hui)路的形式分為：直流接觸(chu)器、交流接觸(chu)器。 按操作機構分為：電磁(ci)式接(jie)觸器、永磁(ci)式接(jie)觸器。 永(yong)磁交流(liu)接觸器是(shi)利用磁極的(de)(de)同性(xing)相斥、用永(yong)磁驅動機構取代傳(chuan)統的(de)(de)電磁鐵驅動機構而形(xing)成的(de)(de)一(yi)種微功耗接觸器國內成熟的(de)(de)產品(pin)型號：CJ20J、NSFC1、NSFC2、NSFC3、NSFC4、NSFC5、NSFC12、NSFC19、CJ40J、NSFMR。 直流接觸(chu)器 直流接(jie)觸器(qi)國(guo)內外的發展狀(zhuang)況 接(jie)觸器總體的發展趨勢將朝著長電氣(qi)壽命、高可靠性、多功能(neng)、環保型(xing)、多規格(ge)、智(zhi)能(neng)化、可通信化的方向(xiang)發展。 混合式(shi)直流接觸器 直流(liu)電(dian)(dian)(dian)流(liu)與交流(liu)電(dian)(dian)(dian)流(liu)相比(bi)較，不存(cun)在周期性的(de)(de)電(dian)(dian)(dian)流(liu)數值過(guo)零點，因此(ci)，傳統接觸(chu)(chu)(chu)器開斷(duan)(duan)電(dian)(dian)(dian)路(lu)(lu)時，觸(chu)(chu)(chu)頭之間(jian)產生的(de)(de)電(dian)(dian)(dian)弧較為(wei)強烈，燃(ran)弧時間(jian)也(ye)比(bi)較長，以便充分釋放(fang)電(dian)(dian)(dian)路(lu)(lu)中剩余(yu)的(de)(de)能量。電(dian)(dian)(dian)弧的(de)(de)燃(ran)燒產生高溫和強光，對觸(chu)(chu)(chu)頭表(biao)面(mian)有嚴(yan)重(zhong)(zhong)的(de)(de)燒蝕作(zuo)用，觸(chu)(chu)(chu)頭材料在多次開斷(duan)(duan)之后逐(zhu)漸流(liu)失，觸(chu)(chu)(chu)頭電(dian)(dian)(dian)磨(mo)損嚴(yan)重(zhong)(zhong)時，導致直流(liu)接觸(chu)(chu)(chu)器報(bao)廢(fei)，不能開斷(duan)(duan)電(dian)(dian)(dian)路(lu)(lu)。 [1] 電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子(zi)技(ji)術得以迅猛(meng)發展，人們將(jiang)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子(zi)元件應用到直(zhi)(zhi)(zhi)流(liu)接(jie)觸(chu)(chu)(chu)器(qi)中，巧妙(miao)的(de)(de)(de)創造出一(yi)種(zhong)混合(he)式直(zhi)(zhi)(zhi)流(liu)接(jie)觸(chu)(chu)(chu)器(qi)，使得直(zhi)(zhi)(zhi)流(liu)接(jie)觸(chu)(chu)(chu)器(qi)向智能化、可控化邁(mai)進了(le)(le)(le)新的(de)(de)(de)一(yi)步(bu)。這種(zhong)混合(he)式接(jie)觸(chu)(chu)(chu)器(qi)利用傳統(tong)(tong)直(zhi)(zhi)(zhi)流(liu)接(jie)觸(chu)(chu)(chu)器(qi)在(zai)閉合(he)導(dao)通狀態(tai)下(xia)觸(chu)(chu)(chu)頭(tou)(tou)接(jie)觸(chu)(chu)(chu)電(dian)(dian)(dian)(dian)(dian)阻小、導(dao)通壓降小的(de)(de)(de)優點(dian)，將(jiang)由反并聯(lian)晶閘(zha)管和控制模塊單(dan)元共同(tong)組成的(de)(de)(de)無觸(chu)(chu)(chu)點(dian)開關(guan)并聯(lian)在(zai)傳統(tong)(tong)直(zhi)(zhi)(zhi)流(liu)接(jie)觸(chu)(chu)(chu)器(qi)觸(chu)(chu)(chu)頭(tou)(tou)上。這種(zhong)無觸(chu)(chu)(chu)點(dian)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子(zi)開關(guan)分(fen)斷電(dian)(dian)(dian)(dian)(dian)路時不(bu)產(chan)生電(dian)(dian)(dian)(dian)(dian)弧(hu)，這就避(bi)免了(le)(le)(le)傳統(tong)(tong)接(jie)觸(chu)(chu)(chu)器(qi)中電(dian)(dian)(dian)(dian)(dian)弧(hu)對觸(chu)(chu)(chu)頭(tou)(tou)材料(liao)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磨損，也就大(da)(da)大(da)(da)增加了(le)(le)(le)觸(chu)(chu)(chu)頭(tou)(tou)的(de)(de)(de)使用壽命和可靠性。
