Chiyambi
Mu zida zamagetsi ndi makina odzipangira okha, ma switch ang'onoang'ono, okhala ndi kukula kwake kochepa komanso magwiridwe antchito abwino kwambiri, akhala zinthu zofunika kwambiri pakukwaniritsa kulamulira kolondola. Mtundu uwu wa switch umakhala ndi mphamvu yodalirika kwambiri yowongolera ma circuit mkati mwa malo ochepa kudzera mu kapangidwe kabwino ka makina ndi luso la zinthu. Pakati pake pali njira zinayi zaukadaulo: njira yogwirira ntchito mwachangu, kukonza bwino malo olumikizirana, kukonza kulimba, ndi kuwongolera ma arc. Kuyambira mabatani a mbewa mpaka zida zamlengalenga, kupezeka kwa ma microswitch kuli paliponse. Kusasinthika kwawo kumachokera ku kugwiritsa ntchito malamulo enieni achilengedwe komanso kufunafuna kwambiri kupanga mafakitale.
Njira zazikulu ndi ubwino waukadaulo
Njira yogwirira ntchito mwachangu
Pakatikati pa microswitch pali njira yake yogwirira ntchito mwachangu, yomwe imasintha mphamvu zakunja kukhala mphamvu yolimba ya bango kudzera mu zigawo zotumizira monga ma levers ndi ma rollers. Mphamvu yakunja ikafika pamtengo wofunikira, bango limatulutsa mphamvu nthawi yomweyo, zomwe zimapangitsa kuti ma contacts amalize kusinthasintha kwa ma on-off pa liwiro la millisecond. Njirayi siili yodalira liwiro la mphamvu yakunja. Ubwino wa njira yogwirira ntchito mwachangu uli pakuchepetsa nthawi ya arc. Pamene ma contacts alekana mwachangu, arc sikhala ikupanga njira yokhazikika ya plasma, motero imachepetsa chiopsezo cha kuchotsedwa kwa kukhudzana. Deta yoyesera ikuwonetsa kuti njira yogwirira ntchito mwachangu imatha kuchepetsa nthawi ya arc kuchokera pa ma millisecond mazana angapo a ma switch achikhalidwe mpaka ma millisecond 5-15, ndikukulitsa moyo wautumiki.
Zatsopano pa Zinthu Zakuthupi
Kusankha zinthu zolumikizirana ndi chinsinsi cha kulimba. Ma alloy asiliva amagwira ntchito bwino kwambiri pamagetsi amphamvu chifukwa cha mphamvu zawo zamagetsi komanso kudziyeretsa okha, ndipo zigawo zawo za oxide zimatha kuchotsedwa ndi mphamvu yamagetsi. Ma alloy a titanium amadziwika kuti ndi opepuka, amphamvu komanso osagwirizana ndi dzimbiri. Ma switch ozindikira mbali zonse ziwiri a ALPS amagwiritsa ntchito ma alloy a titanium, omwe amakhala ndi moyo wamakina mpaka nthawi 10 miliyoni, zomwe ndi zochulukirapo kuposa kasanu kuposa ma alloy achikhalidwe a mkuwa. Ma microswitch omwe ali m'munda wa ndege amagwiritsanso ntchito ma alloy asiliva ophimbidwa ndi golide, monga switch ya Shenzhou-19, yomwe imatha kugwira ntchito popanda zolakwika kwa zaka 20 kutentha kwambiri kuyambira -80 ℃ mpaka 260 ℃, ndipo cholakwika cha kulumikizana ndi chochepera masekondi 0.001.
Kulankhulana kwa mawu
Malo olumikizirana a microswitch nthawi zambiri amapangidwa pakati pa mamilimita 0.25 ndi 1.8. Malo ocheperako awa amakhudza mwachindunji kukhudzika ndi kudalirika. Tengani malo olumikizirana a mamilimita 0.5 mwachitsanzo. Kuyenda kwake kumafuna mamilimita 0.2 okha kuti kuyambitse, ndipo magwiridwe antchito oletsa kugwedezeka amapezeka mwa kukonza zinthu zolumikizirana ndi kapangidwe kake.
Kulamulira kwa Arc
Kuti achepetse arc, microswitch imagwiritsa ntchito njira zosiyanasiyana:
Njira yogwirira ntchito mwachangu: Yesetsani kuchepetsa nthawi yolekanitsa kulumikizana ndikuchepetsa kuchuluka kwa mphamvu ya arc
Kapangidwe ka kuzimitsa moto wa Arc: Arc imaziziritsidwa mwachangu kudzera mu chipinda chozimitsira moto cha ceramic arc kapena ukadaulo wopukutira moto wa gasi.
Kukonza zinthu: Nthunzi yachitsulo yomwe imapangidwa ndi kukhudzana kwa siliva pansi pa mphamvu yayikulu imatha kufalikira mwachangu, kupewa kukhalapo kosalekeza kwa plasma.
Mndandanda wa Honeywell V15W2 wadutsa satifiketi ya IEC Ex ndipo ndi woyenera malo ophulika. Kapangidwe kake kotseka ndi kapangidwe kake kozimitsira arc kangapangitse kuti pasakhale kutayikira kwa arc pamagetsi a 10A.
Kugwiritsa ntchito mafakitale ndi kusasinthika
Zamagetsi zamagetsi za ogula
Zipangizo monga mabatani a mbewa, ma gamepad, ndi ma kiyibodi a laputopu zimadalira ma microswitch kuti zipeze mayankho mwachangu. Mwachitsanzo, nthawi yogwira ntchito ya microswitch ya mbewa ya e-sports iyenera kufika nthawi zoposa 50 miliyoni. Komabe, mndandanda wa Logitech G umagwiritsa ntchito chitsanzo cha Omron D2FC-F-7N (20M). Mwa kukonza kupsinjika kwa kukhudzana ndi kugwedezeka, zimapeza kuchedwa kwa trigger kwa 0.1 milliseconds.
Makampani ndi Magalimoto
Mu makina odzipangira okha a mafakitale, ma microswitch amagwiritsidwa ntchito poyika malo olumikizirana a manja a makina, kuchepetsa malamba otumizira ndi kuwongolera zitseko zachitetezo. Mu gawo la magalimoto, imagwiritsidwa ntchito kwambiri poyambitsa ma airbag, kusintha mipando ndi kuzindikira zitseko. Mwachitsanzo, microswitch ya chitseko cha Tesla Model 3 imagwiritsa ntchito kapangidwe kosalowa madzi ndipo imatha kugwira ntchito mokhazikika pamalo otentha kuyambira -40 ℃ mpaka 85℃.
Zaumoyo ndi Zamlengalenga
Zipangizo zachipatala monga ma ventilator ndi ma monitor zimadalira ma microswitch kuti zikwaniritse kusintha kwa magawo ndi alamu yolakwika. Kugwiritsa ntchito m'munda wa ndege n'kovuta kwambiri. Microswitch ya chitseko cha chipinda cha Shenzhou iyenera kupambana mayeso a kugwedezeka, kugwedezeka ndi kupopera mchere. Chikwama chake chachitsulo chokha komanso kapangidwe kake kosatentha kumatsimikizira chitetezo chokwanira mumlengalenga.
Mapeto
"Mphamvu yayikulu" ya ma microswitch imachokera ku kuphatikiza kwakukulu kwa mfundo zamakina, sayansi ya zida ndi njira zopangira. Kutulutsidwa kwa mphamvu mwachangu kwa njira yogwirira ntchito mwachangu, kulondola kwa micron kwa malo olumikizirana, kupita patsogolo kwa kulimba kwa zinthu za titanium alloy, komanso chitetezo chambiri cha arc control zimapangitsa kuti zisasinthidwe m'munda wowongolera molondola. Ndi kupita patsogolo kwa luntha ndi automation, ma microswitch akupita patsogolo kuti azitha kukhala ochepa, odalirika kwambiri komanso ogwira ntchito zambiri. M'tsogolomu, adzakhala ndi gawo lalikulu m'magawo monga magalimoto atsopano amphamvu, maloboti amafakitale ndi ndege. Gawoli "laling'ono, lamphamvu lalikulu" limapitilizabe kupititsa patsogolo kufufuza kwa anthu malire a kulondola kwa kulamulira.
