當(dāng)轉(zhuǎn)換大負(fù)載直流電流時(shí)，要消除電弧現(xiàn)象，以避免開(kāi)關(guān)觸頭發(fā)生焊接現(xiàn)象。
電弧放電產(chǎn)生高溫，導(dǎo)致觸頭故障，可能引發(fā)事故。
S821D采用內(nèi)部磁鐵靠近觸點(diǎn)消除電弧作用;
額定電流   10A @ 400V DC
觸點(diǎn)電阻： zui大10毫歐
絕緣電阻： 1000兆歐以上在500V DC
絕緣強(qiáng)度： zui低2000V AC至少1分鐘
機(jī)械壽命： 50000次操作以上
搖頭開(kāi)關(guān)的電氣壽命： 10000次操作以上 (對(duì)于10A @ 400V DC 1000次操作以上)
