Cov latches thiab hloov chips yog ubiquitous thiab tuaj yeem siv ntau yam khoom siv los ua kom peb lub neej yooj yim dua. Cov "on-off" switching li no tau dav siv nyob rau hauv tsheb braking systems, kis tau tus mob, qhov rooj xauv thiab lub rooj zaum siv thiab lwm yam khoom. Hauv cov tsheb kauj vab hluav taws xob, cov khoom siv no yog siv rau lub tshuab pedal pab, speedometers, thiab lub cev muaj zog commutation, thiab nyob rau hauv hluav taws xob maus taus, lawv kuj siv los ua cov tswj.
Hauv ib puag ncig hauv tsev, latches thiab hloov khoom siv tau dav siv hauv ntau yam khoom siv hauv tsev ntse. Cov khoom siv no yog siv los xyuas kom meej tias lub qhov rooj ntawm lub tshuab ntxhua khaub ncaws raug kaw; tso saib cov dej theem thiab ntws ntawm lub tshuab kas fes; ntes lub tshuab luam ntawv daim ntawv thauj khoom thiab seb lub hau qhib lossis kaw; thiab tuaj yeem siv rau ntau yam cuab yeej hluav taws xob (lub cev muaj zog thim rov qab, ntsuas qhov chaw, thiab lwm yam).
Lwm daim ntawv thov suav nrog cov tsev ntse (HVAC lub cev muaj zog sib txuas), cov neeg hlau (rau / tawm kev tshawb pom, tsis muaj DC lub cev muaj zog sib hloov, kev tshawb nrhiav qhov kawg, thiab lwm yam), kev tswj hluav taws xob (qhov rooj qhib / kaw, thiab lwm yam), thiab kev noj qab haus huv digital (kev tswj hwm kev noj qab haus huv pab kiag li lawm) lub cev muaj zog commutation, tus pas ntsuas kub waterproof hloov, thiab lwm yam) thiab hais txog.
