Chiyambi
Muzochitika monga kuyendetsa ma elevator, kupanga mafakitale, ndi kuyendetsa galimoto zomwe ndizofunikira kwambiri pachitetezo cha moyo, ngakhale kutikakang'ono switchzingawoneke ngati zosafunika kwenikweni, zimagwira ntchito ngati "mzere wodzitetezera wosawoneka". Kuti zitsimikizire kuti zikugwira ntchito bwino m'machitidwe ofunikira chitetezo, makampaniwa akhazikitsa miyezo yokhwima yotsimikizira, kuonetsetsa kuti switch iliyonse imatha kupirira mayeso achitetezo.
Chida chotetezera cha elevator ndi "bolt" chomwe chimateteza kuyenda mmwamba ndi pansi.
Mu gawo la chitetezo cha elevator,chosinthira chaching'ono ndi "bolt" yofunika kwambiri. Ngati chitseko cha elevator sichinatsekedwe bwino kapena galimoto yapitirira malire a malo, chofananachochosinthira chaching'ono idzachotsa nthawi yomweyo dera ndikukakamiza elevator kuti ileke kugwira ntchito. Mwachitsanzo, mu zida zotsekera za chitseko cha pansi ndi chitseko cha galimoto,chosinthira chaching'ono amatha kuzindikira bwino ngati chitseko chatsekedwa kwathunthu. Bola ngati pali mpata pang'ono, izi zingayambitse chitetezo. Ma switch otere ayenera kupambana mayeso ovuta kuti atsimikizire kuti salephera pambuyo pa ntchito zambirimbiri zotsegula ndi kutseka zitseko, zomwe zimapangitsa kuti pakhale chotchinga chachitetezo kwa wokwera aliyense mu elevator.
Maloko a zitseko zachitetezo m'mafakitale ndi "oteteza zipata" popewa zochitika mwangozi.
M'mafakitale, zitseko zachitetezo zimakhala ndi malokochosinthira chaching'onondi "alonda a pachipata" popewa ngozi. Zipangizo zikamagwira ntchito, bola ngati wina akuyesera kutsegula chitseko choteteza,chosinthira chaching'ono idzadula mphamvu mwachangu ndikupangitsa kuti zidazo ziyime mwachangu kuti wogwiritsa ntchito asavulazidwe ndi zida zozungulira mwachangu. Mphamvu yamagetsi ndi liwiro la ma switch awa ali ndi malamulo okhwima, ndipo ayenera kuchitapo kanthu mkati mwa ma millisecond kuti awonjezere "inshuwaransi iwiri" pakupanga mafakitale.
Machitidwe achitetezo a magalimoto ndi "zotumiza" zizindikiro zoyendetsera mabuleki.
Maswichi a magetsi a mabuleki, maswichi olumikizirana ndi ma airbag otetezeka, ndi zina zotero, zonse ndizofunikira kwambiri.chosinthira chaching'onokuonetsetsa kuti galimotoyo ili bwino. Mukayimitsa, chosinthira magetsi cha brake chimatumiza chizindikiro nthawi yomweyo, kuunikira magetsi a brake ndikuyambitsa makina a ABS;chosinthira chaching'ono Sensa ya malo a mpando idzasintha mphamvu yotulukira ya thumba la mpweya lachitetezo malinga ndi momwe wokwerayo akhalira. Kukhazikika kwa ma switch awa kumakhudza mwachindunji chitetezo cha magalimoto. Ngati alephera, angayambitse ngozi monga kugundana kumbuyo ndi kuphulika mwangozi kwa thumba la mpweya. Chifukwa chake, kudalirika kwawo ndikokwera kwambiri.
Chitsimikizo cha chitetezo ndi "inshuwaransi iwiri" yodalirika.
Kuonetsetsa kuti ntchito ya micro micro ikuyenda bwino Ma switch mu machitidwe ofunikira chitetezo, pali miyezo yovomerezeka monga ISO 13849 ndi IEC 61508. Miyezo iyi ili ngati "mayeso ofotokozera", kuyika zizindikiro zokhwima malinga ndi nthawi ya switch, kuthekera koletsa kusokoneza, komanso kusinthasintha kumadera ovuta kwambiri. Panthawi yopereka satifiketi, ma switch ayenera kuyesedwa kangapo monga kutentha kwambiri, kugwedezeka, ndi fumbi, mwachitsanzo, mu satifiketi ya ISO 13849, ma switch ayenera kupambana mayeso ambirimbiri a kuzungulira kuti atsimikizire kuti sadzalephera mwadzidzidzi pakugwiritsa ntchito kwa nthawi yayitali. Zinthu zomwe zapambana satifiketi zokha ndi zomwe zingagwiritsidwe ntchito mu machitidwe ofunikira chitetezo.
Mapeto
Kakang'ono Ma switch mu makina ofunikira chitetezo amagwiritsa ntchito njira zolondola kuti ateteze moyo ndi chitetezo cha kupanga. Miyezo yokhwima ya satifiketi imawonjezera "inshuwaransi iwiri" ku kudalirika kwawo, kuonetsetsa kuti choyambitsa chilichonse chili cholondola komanso chopanda zolakwika. Ndi kukulitsa chidziwitso cha chitetezo, ma switch ang'onoang'ono awa adzapitirizabe kukhala alonda m'bwalo lankhondo losawoneka ndikukhala mphamvu zodalirika zofunika kwambiri mu dongosolo la chitetezo.
