8.56.AA.62為單動作開放式線(xian)性電(dian)(dian)磁(ci)。只要線(xian)圈(quan)通電(dian)(dian)，柱塞(sai)就可以(yi)開啟(qi)電(dian)(dian)源(yuan)并保持。關(guan)閉電(dian)(dian)源(yuan)，柱塞(sai)被釋(shi)放，并通過外(wai)力(li)(li)返回(hui)到(dao)(dao)起(qi)始(shi)(shi)位(wei)(wei)置(zhi)。當柱塞(sai)運動開始(shi)(shi)時和當電(dian)(dian)磁(ci)配有連(lian)續額定線(xian)圈(quan)時，實現較小的力(li)(li)。柱塞(sai)處(chu)于起(qi)始(shi)(shi)位(wei)(wei)置(zhi)（柱塞(sai)外(wai)側，推力(li)(li)銷在內部），由外(wai)力(li)(li)釋(shi)放或維持。線(xian)圈(quan)通電(dian)(dian)，柱塞(sai)關(guan)閉停止，拉動聯(lian)接機構，推力(li)(li)銷推出。關(guan)閉電(dian)(dian)源(yuan)，柱塞(sai)和推力(li)(li)銷通過外(wai)力(li)(li)返回(hui)到(dao)(dao)起(qi)始(shi)(shi)位(wei)(wei)置(zhi)。
