Relay bụ ihe na-agbanwe agbanwe na-akpaghị aka na ọrụ dịpụrụ adịpụ, mgbe mgbanwe nke mkpali na sekit ntinye aka ruru uru a kapịrị ọnụ, ọ nwere ike ime ka sekit mmepụta nke ike a na-achịkwa na mgbanwe nzọụkwụ a kara aka na ngwaọrụ nchịkwa akpaka.O nwere usoro nhụta iji meghachi omume na mkpali mpụga (ọkụ eletrik ma ọ bụ na-abụghị eletrik), onye na-eme ihe iji chịkwaa “on” na “ gbanyụọ” nke sekit a na-achịkwa, yana usoro ntụnyere etiti iji tụnyere, kpee ikpe na ịtụgharị ịdị ukwuu nke mkpali.A na-eji relays eme ihe na njikwa anya, telemetry, nzikọrịta ozi, njikwa akpaka, mechatronics, na teknụzụ ikuku iji jikwaa, chekwaa, hazie na ịnye ozi.

Relays n'ozuzu nwere usoro ntinye (akụkụ ntinye) nke na-egosipụta ụfọdụ mgbanwe ntinye (dị ka ugbu a, voltaji, ike, impedance, ugboro, okpomọkụ, nrụgide, ọsọ, ọkụ, wdg);onye na-eme ihe (akụkụ mmepụta) nke na-achịkwa sekit a na-achịkwa "na" na "gbanyụọ";na usoro dị n'etiti (akụkụ ụgbọala) nke ndị di na nwunye na-ekewapụ ọnụ ọgụgụ ntinye, na-edozi ọrụ ahụ ma na-ebugharị akụkụ mmepụta n'etiti akụkụ ntinye na mmepụta.N'agbata akụkụ ntinye na mmepụta nke relay, e nwere usoro etiti (akụkụ ụgbọala) nke di na nwunye na-ekewapụ ntinye, na-edozi ọrụ ahụ ma na-ebugharị mmepụta.
