1. Tanthauzo la relay: mtundu wa chipangizo chodziwongolera chomwe chimayambitsa kulumpha-kusintha kwa zotulutsa pamene kuchuluka kwa zolowetsa (magetsi, maginito, phokoso, kuwala, kutentha) kufika pamtengo wina.
1. Mfundo yogwirira ntchito ndi makhalidwe a ma relay: Pamene kuchuluka kwa kulowetsa (monga voteji, panopa, kutentha, etc.) kufika pamtengo wotchulidwa, kumayendetsa dera lotulutsa kuti lizitse kapena kuzimitsa.Relays akhoza kugawidwa m'magulu awiri: magetsi (monga panopa, voteji, mafupipafupi, mphamvu, etc.) relays ndi sanali magetsi (monga kutentha, kuthamanga, liwiro, etc.) relays.
Iwo ali ndi ubwino wa kuchitapo kanthu mofulumira, ntchito yokhazikika, moyo wautali wautumiki, ndi kukula kochepa.Amagwiritsidwa ntchito kwambiri poteteza mphamvu, makina, kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. amadziwikanso kuti gawo lotulutsa).Nthawi zambiri amagwiritsidwa ntchito pazigawo zowongolera zokha.
Iwo kwenikweni ndi mtundu wa "automatic switch" yomwe imagwiritsa ntchito kachidutswa kakang'ono kuwongolera mphamvu yayikulu.Chifukwa chake, amatenga gawo pakusintha kodziwikiratu, chitetezo chachitetezo, komanso kusinthana kozungulira mudera.1.Mfundo yogwirira ntchito ndi mawonekedwe a ma electromagnetic relay: ma elekitiromagineti relay nthawi zambiri amakhala ndi zitsulo zachitsulo, ma coils, armatures, ndi akasupe olumikizirana.Malingana ngati voteji ina ikugwiritsidwa ntchito kumapeto kwa koyilo, mphamvu ina imadutsa pa koyilo, ndikupanga mphamvu yamagetsi.
Chombocho chidzakopeka pachimake chachitsulo ndi mphamvu yamagetsi yamagetsi, kugonjetsa mphamvu yokoka ya kasupe wobwerera, ndipo motero kubweretsa kukhudzana kwamphamvu kwa zida ndi kukhudzana koyima (nthawi zambiri kutseguka) palimodzi.Koyiloyo ikachotsedwa mphamvu, mphamvu yamagetsi yamagetsi imasowa, ndipo zida zimabwerera pamalo ake pomwe zimabwereranso kasupe, kupangitsa kulumikizana kwamphamvu ndi kulumikizana koyambirira (komwe kumatsekedwa) palimodzi.
Mwanjira iyi, kudzera muzochita zokopa ndi kumasulidwa, dera likhoza kuyatsidwa ndi kutsekedwa.Kwa olumikizana nawo "otseguka, otsekedwa" a relay, amatha kusiyanitsa motere: kulumikizana koyima komwe kumalumikizidwa pomwe koyilo yopatsirana sikuli ndi mphamvu imatchedwa "kulumikizana kotseguka"
