德國FANAL一般是(shi)使(shi)用(yong)“電(dian)(dian)(dian)(dian)(dian)接(jie)點(dian)(dian)壓(ya)(ya)(ya)力表”，這是(shi)一種普通(tong)的(de)(de)(de)管彈簧壓(ya)(ya)(ya)力表，加上兩(liang)組電(dian)(dian)(dian)(dian)(dian)接(jie)點(dian)(dian)。可(ke)以(yi)接(jie)通(tong)相當高低壓(ya)(ya)(ya)力的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)接(jie)點(dian)(dian)，從而(er)把(ba)壓(ya)(ya)(ya)力控制(zhi)在(zai)上下限之間。這種電(dian)(dian)(dian)(dian)(dian)接(jie)點(dian)(dian)的(de)(de)(de)容(rong)量(liang)小，只能開(kai)(kai)(kai)關接(jie)觸(chu)(chu)器(qi)的(de)(de)(de)控制(zhi)線(xian)圈，壓(ya)(ya)(ya)力表上的(de)(de)(de)控制(zhi)位(wei)置可(ke)以(yi)調節(jie)。FANAL行程(cheng)開(kai)(kai)(kai)關是(shi)一種根據運(yun)動部件的(de)(de)(de)行程(cheng)位(wei)置而(er)切(qie)換(huan)電(dian)(dian)(dian)(dian)(dian)路的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)器(qi)，它的(de)(de)(de)作用(yong)原(yuan)理(li)與按鈕類似。FANAL行程(cheng)開(kai)(kai)(kai)關廣泛用(yong)于各類機床和起重機械，用(yong)以(yi)控制(zhi)其行程(cheng)、進(jin)行終(zhong)端(duan)限位(wei)保(bao)護(hu)(hu)。FANAL熱(re)繼電(dian)(dian)(dian)(dian)(dian)器(qi)就是(shi)利用(yong)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)熱(re)效應原(yuan)理(li)，在(zai)出現(xian)電(dian)(dian)(dian)(dian)(dian)動機不(bu)能承受的(de)(de)(de)過載時(shi)切(qie)斷電(dian)(dian)(dian)(dian)(dian)動機電(dian)(dian)(dian)(dian)(dian)路，為電(dian)(dian)(dian)(dian)(dian)動機提供(gong)過載保(bao)護(hu)(hu)的(de)(de)(de)保(bao)護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)器(qi)。FANAL直流(liu)(liu)接(jie)觸(chu)(chu)器(qi)的(de)(de)(de)工作原(yuan)理(li)是(shi)當接(jie)觸(chu)(chu)器(qi)線(xian)圈通(tong)電(dian)(dian)(dian)(dian)(dian)后，線(xian)圈電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)產生磁場，使(shi)靜鐵(tie)心產生電(dian)(dian)(dian)(dian)(dian)磁吸力吸引動鐵(tie)心，并(bing)帶(dai)動觸(chu)(chu)點(dian)(dian)動作：常(chang)閉(bi)觸(chu)(chu)點(dian)(dian)斷開(kai)(kai)(kai)，常(chang)開(kai)(kai)(kai)觸(chu)(chu)點(dian)(dian)閉(bi)合，兩(liang)者是(shi)聯動的(de)(de)(de)。
