Relay ey’ekigendererwa ekya bulijjo-kitundu kya buuma ekikozesebwa ennyo mu kufuga circuit. Ebintu byayo ebikulu bye bino: obusobozi obw’enjawulo obw’amaanyi, obwesigwa obw’amaanyi, okufuga okutuufu okw’amaanyi, okukyusakyusa okw’amaanyi, n’obunene obutono.
Relay ey’ekigendererwa ekya bulijjo-kitundu kya masanyalaze ekya bulijjo ekikozesebwa okufuga siginiini y’amasannyalaze mu nkulungo nga bagiggulawo oba nga bagiggalawo, bwe kityo ne kiyunga oba okukutula ekiyungo.
General-purpose relay kye kyuma ekifuga amasannyalaze ekikyusa embeera y’okukyusakyusa ya siginiini efuluma nga kifuga siginiini eyingizibwa. Relay ey’ekigendererwa ekya bulijjo-etera okubaamu koyilo, ebikwatagana, n’omusingi gw’ekyuma ogutakyuka. Koyilo bw’ecamulwa akasannyalazo, ekola ekifo kya magineeti, ekivaako ebikwatagana okuggalawo oba okugguka, bwe kityo ne kifuga siginiini y’amasannyalaze mu nkulungo. General-purpose relay kitundu kya masanyalaze ekya bulijjo ekikozesebwa okufuga siginiini y’amasannyalaze mu circuit nga bagiggulawo oba nga bagiggalawo, bwe kityo ne kiyunga oba okukutula circuit.
