機頂盒開關維修方面： 　　

機頂盒開關的主要(yao)故(gu)障(zhang)是接(jie)(jie)觸(chu)不(bu)良(即(ji)接(jie)(jie)觸(chu)電阻(zu)(zu)大(da)于0.5Ω)，即(ji)滑動(dong)片與(yu)接(jie)(jie)觸(chu)片間有一定阻(zu)(zu)值或(huo)(huo)時大(da)時小甚至斷路。例如會(hui)造成收音(yin)機完全無聲、聲音(yin)時有時無、波段低(di)端本振(zhen)或(huo)(huo)靈敏度(du)低(di)等故(gu)障(zhang)。處理(li)方法如下：  　　

(1)機(ji)頂(ding)盒(he)開(kai)(kai)關(guan)(guan)(guan)(guan)  由于動(dong)(dong)(dong)、定觸(chu)(chu)(chu)(chu)點(dian)(dian)外(wai)露，可直接用(yong)無(wu)水(shui)酒(jiu)精(jing)滴(di)入各動(dong)(dong)(dong)、定觸(chu)(chu)(chu)(chu)點(dian)(dian)之(zhi)(zhi)間，同時(shi)不斷轉(zhuan)動(dong)(dong)(dong)波段開(kai)(kai)關(guan)(guan)(guan)(guan)的轉(zhuan)柄，使(shi)各動(dong)(dong)(dong)、定觸(chu)(chu)(chu)(chu)點(dian)(dian)摩(mo)擦去除污垢和氧化層，并充分清洗。若有定觸(chu)(chu)(chu)(chu)簧(huang)片(pian)與刀觸(chu)(chu)(chu)(chu)片(pian)不能正常接觸(chu)(chu)(chu)(chu)時(shi)，可用(yong)攝子調整觸(chu)(chu)(chu)(chu)點(dian)(dian)簧(huang)片(pian)，使(shi)之(zhi)(zhi)接觸(chu)(chu)(chu)(chu)緊密。有時(shi)，波段開(kai)(kai)關(guan)(guan)(guan)(guan)中可能有某組開(kai)(kai)關(guan)(guan)(guan)(guan)未用(yong)，則可作(zuo)為代換備(bei)用(yong)組。  　　(2)機(ji)頂(ding)盒(he)開(kai)(kai)關(guan)(guan)(guan)(guan)由于這種開(kai)(kai)關(guan)(guan)(guan)(guan)為密封(feng)開(kai)(kai)關(guan)(guan)(guan)(guan)，外(wai)殼不易(yi)打(da)開(kai)(kai)，故酒(jiu)精(jing)等清洗液只能設法從滑動(dong)(dong)(dong)間隙處滴(di)入開(kai)(kai)關(guan)(guan)(guan)(guan)內部，同時(shi)不斷撥動(dong)(dong)(dong)轉(zhuan)柄，使(shi)各觸(chu)(chu)(chu)(chu)點(dian)(dian)充分清洗，使(shi)之(zhi)(zhi)接觸(chu)(chu)(chu)(chu)良好，并消除漏電。
