德國FANAL一般(ban)是(shi)使用(yong)“電(dian)(dian)接(jie)(jie)點(dian)(dian)壓力(li)(li)表”，這(zhe)(zhe)是(shi)一種(zhong)普通(tong)的(de)(de)(de)管彈簧壓力(li)(li)表，加上兩組電(dian)(dian)接(jie)(jie)點(dian)(dian)。可以接(jie)(jie)通(tong)相當(dang)(dang)高低壓力(li)(li)的(de)(de)(de)電(dian)(dian)接(jie)(jie)點(dian)(dian)，從而(er)把壓力(li)(li)控(kong)(kong)制(zhi)在上下限(xian)之(zhi)間。這(zhe)(zhe)種(zhong)電(dian)(dian)接(jie)(jie)點(dian)(dian)的(de)(de)(de)容量小(xiao)，只能(neng)開(kai)關(guan)接(jie)(jie)觸(chu)器(qi)(qi)的(de)(de)(de)控(kong)(kong)制(zhi)線圈，壓力(li)(li)表上的(de)(de)(de)控(kong)(kong)制(zhi)位置可以調節。FANAL行(xing)程(cheng)(cheng)開(kai)關(guan)是(shi)一種(zhong)根據運(yun)動(dong)部件的(de)(de)(de)行(xing)程(cheng)(cheng)位置而(er)切(qie)換(huan)電(dian)(dian)路(lu)的(de)(de)(de)電(dian)(dian)器(qi)(qi)，它的(de)(de)(de)作用(yong)原(yuan)(yuan)理(li)(li)與按鈕類(lei)似。FANAL行(xing)程(cheng)(cheng)開(kai)關(guan)廣泛用(yong)于各類(lei)機(ji)床和起重機(ji)械(xie)，用(yong)以控(kong)(kong)制(zhi)其(qi)行(xing)程(cheng)(cheng)、進行(xing)終端(duan)限(xian)位保護(hu)(hu)。FANAL熱(re)繼(ji)電(dian)(dian)器(qi)(qi)就是(shi)利用(yong)電(dian)(dian)流的(de)(de)(de)熱(re)效應原(yuan)(yuan)理(li)(li)，在出現電(dian)(dian)動(dong)機(ji)不能(neng)承受的(de)(de)(de)過載時切(qie)斷(duan)電(dian)(dian)動(dong)機(ji)電(dian)(dian)路(lu)，為電(dian)(dian)動(dong)機(ji)提供過載保護(hu)(hu)的(de)(de)(de)保護(hu)(hu)電(dian)(dian)器(qi)(qi)。FANAL直流接(jie)(jie)觸(chu)器(qi)(qi)的(de)(de)(de)工(gong)作原(yuan)(yuan)理(li)(li)是(shi)當(dang)(dang)接(jie)(jie)觸(chu)器(qi)(qi)線圈通(tong)電(dian)(dian)后，線圈電(dian)(dian)流產生磁場，使靜鐵(tie)心產生電(dian)(dian)磁吸(xi)力(li)(li)吸(xi)引動(dong)鐵(tie)心，并帶動(dong)觸(chu)點(dian)(dian)動(dong)作：常(chang)(chang)閉(bi)觸(chu)點(dian)(dian)斷(duan)開(kai)，常(chang)(chang)開(kai)觸(chu)點(dian)(dian)閉(bi)合(he)，兩者(zhe)是(shi)聯動(dong)的(de)(de)(de)。
