Mwinamwake mwawonapo kusintha kwazing'ono mu mitundu yosiyanasiyana ya zipangizo, koma mwina simukudziwa dzina lonse la mankhwalawa. Mawu akuti switch yaying'ono amatanthauza chosintha chaching'ono chosintha. Dzinalo limaperekedwa chifukwa chosinthana kotere kumafunikira mphamvu zochepa kuti zithe kuyambitsa. Munkhaniyi, tiwona mozama za mayunitsi awa. Werengani kuti mumve zambiri.

Choyambirira, ndikofunikira kukumbukira kuti mayunitsiwa amatha kupezeka pazida zambiri, monga zida zamagetsi ndi ma circuits amagetsi. Popeza izi sizikufuna kuyesetsa kwambiri kuti zitheke, zitha kukhala zosankha zabwino pamakina, zida zamafakitale, uvuni wama microwave, ndi zikepe kungotchulapo ochepa. Kupatula izi, atha kugwiritsidwa ntchito mgalimoto zambiri. M'malo mwake, sitingathe kuwerengera kuchuluka kwa zida zamagetsi zomwe amagwiritsa ntchito.

Chiyambi

Ponena za komwe zimayambira izi, zidayambitsidwa patadutsa nthawi yayitali magulu ena omwe amagwiranso ntchito yomweyo. Kwa nthawi yoyamba, switch yaying'ono idapangidwa mu 1932 ndi katswiri wotchedwa Peter McGall.

Zaka makumi angapo pambuyo pake, Honeywell Sensing and Control adagula kampaniyo. Ngakhale chizindikirocho chimakhalabe cha Honeywell, opanga ena ambiri amapanga masinthidwe ang'onoang'ono omwe amagawana chimodzimodzi.

Kodi Amagwira Ntchito Motani?

Chifukwa cha kapangidwe ka mayunitsiwa, amatha kutsegula ndikutseka magetsi pakamphindi. Ngakhale atapanikizika pang'ono, dera limatha kupitilirabe ndikukhazikika potengera kapangidwe kake ndikusintha kwa switch.

Kusinthana kuli ndi kasupe mkati mwake. Zimayamba chifukwa cha kuyenda kwa lever, batani, kapena roller. Pakapanikizika pang'ono pothandizidwa ndi kasupe, zomwe zimachitika mwachangu zimachitika mkatikati mwa kachingwe kamphindi. Chifukwa chake, titha kunena kuti magwiridwe antchito a mayunitsi awa ndiosavuta komanso ofunika kwambiri.

Izi zikachitika, mzere wamkati wagawo umatulutsa mawu osindikiza. Mutha kusintha mphamvu yakunja yomwe ingayambitse kusinthana. Mwanjira ina, mutha kusankha momwe zingagwiritsire ntchito zovuta kuti musinthe.

Ngakhale ma switch awa ali ndi kapangidwe kosavuta, ndimayankhidwe mwachangu a chipindacho omwe amapangitsa kuti ikhale chisankho choyenera pamachitidwe osiyanasiyana pano ndi pano. Chifukwa chake, izi zidalowa m'malo mwa zinthu zina zambiri zomwe zidayambitsidwa kale. Chifukwa chake, nditha kunena kuti masinthidwe awa amayendetsa mabwalo mozungulira mayunitsi ena ambiri omwe mungapeze pamsika.

Chifukwa chake, ichi chinali chiyambi cha momwe ma microswitches amagwirira ntchito komanso zomwe mungayembekezere kuchokera kwa iwo. Ngati mukufuna kupindula nazo, tikukulimbikitsani kuti muwagule ku kampani yabwino. Kupatula apo, simukufuna kukhala ndi gawo lolakwika. Chifukwa chake, kusankha gawo labwino kwambiri ndikumvetsetsa kwanzeru.
