Isilawuli esilula kakhulu iswishi exhuma injini kugesi, njengasezintweni ezincane zasendlini noma amathuluzi kagesi. Iswishi ingasebenza ngesandla noma iqalwe ngokuzenzakalela noma iyekwe ukusebenzisa ama-relay noma izixhumi ezixhunywe kuzinzwa. Iswishi ingaba nezindawo ezikhethiwe ezihlukile, okuvumela injini ukuthi ixhume kugesi ngezindlela ezihlukene, njengokunciphisa i-voltage yokuqala, ukuhlehlisa ukusebenza, noma ukukhetha isivinini esihlukile. Izilawuli ezincane zingase zishiye ukulayishwa okukhulu kanye namadivayisi okuvikela adlule, zithembele kumasekhethi angaphandle okuvikela okudlulele ukuze kunqandwe amandla amaningi. Amanye amamotho amancane akhelwe-ngokuvikela ukugcwala kakhulu okuvula ngokuzenzakalelayo isekethe ukuvimbela ukugcwala. Amamotho amakhudlwana azoba nokulayishwa okuningi okudluliselwe noma izinga lokushisa{6}}nezinzwa ezidluliswayo, kanye namafuse noma ama-circuit breaker angezwe kusilawuli ukuze kuvinjelwe ukudlulela. Izilawuli zezimoto ezizenzakalelayo zingase futhi zifake amaswishi anomkhawulo noma amanye amadivaysi ukuvikela imishini.
Izilawuli zezimoto eziyinkimbinkimbi zingakwazi ukulawula ngokunembile isivinini kanye ne-torque yemoto futhi zingase zibe yingxenye-yesistimu yokulawula iluphu evaliwe yokulawula ukuma kwemishini.
