A tlangpi in
Switch luhternak relay chuahnak hna i a tliknak kilvennak riantuannak he aa thenmi himnak khamnak, cu nih cun ttihnung hmun ah a ummi switch pehtlaihnak asiloah a naihmi switch hna in himnak khamnak hmun ah himnak khamnak chungin chuahnak relay he himnak hmun ah luhternak signal kha a thleidan i a kuat. Line palhnak hmuh khawhnak cu a dang relay chuahnak in hmuh khawh a si i module cunglei LED ah langhter 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.
