Relay ya general-purpose ni chinthu cha magesi chakumanyikwa chomene icho chikugwiriskirika nchito kuti chilongozge chimanyikwiro cha magesi mu dera mwa kuchijura panji kuchijara, ntheura chikulumikizga panji kuwuskapo dera.
General-purpose relay ni chipangizo chakulaŵilira magesi icho chikulongozga kusintha kwa chimanyikwiro chakufumamo mwa kulaŵilira chimanyikwiro chakunjira. Relay ya general-yikuŵa na coil, makontakti, na chisulo chakukhora. Para coil iyi yakhuŵilizgika na magesi, yikupanga magnetic field, ndipo ivi vikupangiska kuti vigaŵa ivyo vikukhwaskana na magesi vijalike panji kujulika, ndipo ntheura vikulaŵilira chimanyikwiro cha magesi icho chili mu dera.
