Neno wi lembe
Jam gwoko kwo ma juketho kende ku switch input transistor output, ma poko man cwalu lembe ma wok kud i switch contacts nyo proximity loko kabedo ma rac ni kabedo ma ber ku transistor ma wok woko nikadhu kud i dhugola mi gwoko kwo. Nwangu peko mi lain tiyere nikadhu kud i LED iwi wi module. Dial switch pa module jutiyo kudu ni ketho piny ma donjo man ma wok woko in-phase nyo reverse control, man ni ketho nyo juku tic mi nyuthu alarm mi nwangu peko.
Piny eni mitu kero ma tiye kende, ku kero ma tiye kende mi mio, mi ketho, man mi wodhu.
