1. Wehewehe 'ana o ka relay: he 'ano o ka 'akomi mana mana e ho'ololi i ka lele-ho'ololi 'ana i ka puka 'ana ke hiki aku ka nui hookomo (ka uila, magnetism, kani, malamalama, wela) i kekahi waiwai.
1. ʻO ke kumu hana a me nā hiʻohiʻona o nā relays: Ke hiki i ka nui hoʻokomo (e like me ka volta, ka manawa, ka mahana, a me nā mea ʻē aʻe) i kahi waiwai i ʻōlelo ʻia, hoʻomalu ia i ke kaapuni puka e hoʻohuli ʻia a i ʻole.Hiki ke hoʻokaʻawale ʻia nā relays i ʻelua mau ʻāpana: nā uila (e like me ka manawa, ka uila, ka pinepine, ka mana, a me nā mea ʻē aʻe) nā relay a me nā mea uila ʻole (e like me ka mahana, ke kaomi, ka wikiwiki, a me nā mea ʻē aʻe).
Loaʻa iā lākou nā pōmaikaʻi o ka hana wikiwiki, ka hana paʻa, ke ola lawelawe lōʻihi, a me ka liʻiliʻi liʻiliʻi.Hoʻohana nui ʻia lākou i ka pale mana, automation, motion control, remote control, ana ana, kamaʻilio, a me nā mea hana ʻē aʻe. ʻike ʻia hoʻi he kaapuni puka).Hoʻohana pinepine ʻia lākou i nā kaʻa kaʻa kaʻa.
He ʻano ʻano "hoʻololi aunoa" lākou e hoʻohana ana i kahi au liʻiliʻi e hoʻomalu i kahi au nui.No laila, pāʻani lākou i ka hoʻoponopono ʻakomi, palekana palekana, a me ka hoʻololi kaapuni i ke kaapuni.1.ʻO ke kumu hana a me nā hiʻohiʻona o nā relay electromagnetic: ʻO nā relay electromagnetic maʻamau i loko o nā cores hao, coils, armatures, a me nā puna pili.I ka lōʻihi o ka hoʻohana ʻia ʻana o kekahi volta ma nā ʻaoʻao ʻelua o ka coil, e kahe ana kekahi au i loko o ka coil, e hana ana i kahi hopena electromagnetic.
E hoʻoneʻe ʻia ka armature i ke kumu hao e ka ikaika electromagnetic, e lanakila ana i ka ikaika huki o ka pūnāwai hoʻi, a pēlā e lawe pū ai i ka pili ikaika o ka armature a me ka pilina paʻa (maʻamau wehe ʻia).Ke hoʻopau ʻia ka coil, nalowale ka mana electromagnetic, a hoʻi ka armature i kona kūlana mua ma lalo o ka hana a ka pūnāwai hoʻi, e hana pū ana i ka pilina ikaika a me ka pilina paʻa kumu (pili paʻa maʻamau).
Ma kēiaʻano, ma o ka hana o ka huki a me ka hoʻokuʻuʻana, hiki ke hoʻohuli a hoʻopau i ke kaapuni.No nā pilina "wehe maʻamau, pani maʻamau" o ka relay, hiki ke hoʻokaʻawale ʻia lākou ma kēia ʻano: ʻo ka pilina paʻa i ka moku i hoʻokaʻawale ʻia ke hoʻoikaika ʻole ʻia ka relay coil i kapa ʻia ʻo "normally open contact"
