Switch luhternak transistor chuahnak i a tthawnnak kilvennak riantuannak he a dang tein chiahmi himnak khamnak, cu nih cun ttihnung hmun ah switch pehtlaihnak asiloah a naihnak switch hna in himnak khamnak hmun ah himnak khamnak chungin chuahnak transistor he himnak hmun ah luhternak signal kha a thleidan i a kuat. Line palhnak hmuh khawhnak cu module cunglei ah LED hmangin tuah khawh a si. Module i dial switch cu in-phase asiloah hnulei uknak luhternak le chuahnak chiahnak caah hman a si, cun line palhnak hmuh khawhnak ralrin peknak riantuannak kha on le phih khawhnak caah hman a si. Hi thilri nih hin a dang tein mei a herh, a dang tein mei a herh, luhternak le chuahnak terminal hna he.
