Ukudluliselwa kwexeshasisixhobo sokulawula esisebenzisa umgaqo we-electromagnetic okanye umgaqo we-mechanical ukufikelela kulawulo lokulibaziseka kwexesha. Ineentlobo ezininzi, ezifana nohlobo lokudambisa umoya, uhlobo lombane kunye nohlobo lwe-elektroniki. Iireyi zexesha zinokwahlulwa zibe ziintlobo ezimbini: uhlobo lokulibaziseka kwexesha olunamandla kunye nohlobo lokulibaziseka kwexesha lokucima umbane. Iireyi zexesha ezidampiweyo emoyeni zinoluhlu olukhulu lokulibaziseka (0.4 ~ 60s kunye ne-0.4 ~ 180s), zilula ngesakhiwo, kodwa azichanekanga kangako.
Xa ikhoyili inikwe amandla, i-armature kunye neepallets zitsalwa yi-core kwaye ziyehla ngoko nangoko, zenze ukuba intshukumo ikhawuleze ivele okanye ivale. Kodwa intonga yepiston kunye ne-lever azinakulandela i-armature kunye nokuhla, kuba isiphelo esiphezulu sentonga yepiston siqhagamshelwe kwi-membrane yerabha kwigumbi lomoya, xa intonga yepiston ekukhutshweni kwentwasahlobo iqala ukuhamba, i-membrane yerabha iyehla, igumbi lomoya elingaphezulu komoya liba lincinci kwaye intonga yepiston iyamanzi kwaye iwele kancinci. Emva kwexesha elithile, intonga yepiston iyehla iye kwindawo ethile, iya kutyhala intshukumo yoqhagamshelwano lokulibaziseka nge-lever, ukuze i-dynamic break contact ivale, i-dynamic contact ivale. Ukusuka kwi-coil enikwe amandla ukuya kwi-time delay contact ukuze kugqitywe intshukumo, ngeli xesha lixesha lokulibaziseka kwe-relay. Ubude bexesha lokulibaziseka bungatshintshwa ngokulungelelanisa ubungakanani bomngxuma wokungena wegumbi lomoya ngesikrufu. Emva kokuba i-attraction coil incitshisiwe amandla, i-relay iyabuya ngesenzo se-recovery spring. Umoya ukhutshwa ngokukhawuleza ngomngxuma wokuphuma komoya.
