Taw qhia
Pushbutton keyboardsyog ubiquitous Cheebtsam nyob rau hauv ntau yam khoom siv hluav taws xob, xws li cov khoom siv hauv tsev mus rau kev siv tshuab.Txawm hais tias lawv qhov yooj yim, cov keyboards no ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej ntws ntawm hluav taws xob thiab txiav txim siab ua haujlwm ntawm cov khoom siv uas lawv nyob.Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv lub puab ua hauj lwm ntawm pushbutton keyboards thiab sib tham txog lawv ntau yam thiab daim ntawv thov.
Lub hauv paus ntawm Pushbutton Switches
Ntawm nws cov tub ntxhais, lub laub khawm hloov yog ib qho yooj yim electromechanical ntaus ntawv uas tso cai los yog cuam tshuam cov ndlwg ntawm hluav taws xob tam sim no los ntawm kev sib txuas los yog disconnecting hluav taws xob tiv tauj.Lub tshuab hluav taws xob muaj ntau yam tseem ceeb:
1. Actuator: Tus actuator yog ib feem ntawm qhov hloov pauv uas tus neeg siv nias kom qhib qhov hloov.Nws feem ntau yog tsim los kom yooj yim rau nias thiab tuaj yeem ua ntau yam duab thiab ntau thiab tsawg, nyob ntawm daim ntawv thov.
2. Kev sib cuag: Kev sib cuag yog cov khoom siv hluav taws xob uas ua rau lossis tawg qhov hluav taws xob sib txuas.Lawv feem ntau yog ua los ntawm cov hlau thiab tuaj yeem tsim tau raws li ib txwm qhib (NO) lossis ib txwm kaw (NC) kev sib cuag.
3. Housing: Lub vaj tse nyob rau hauv cov khoom siv hloov pauv thiab muab kev tiv thaiv los ntawm lwm yam xws li plua plav, ya raws, thiab kev ntxhov siab.
Mechanism
Thaum tus neeg siv nias lub actuator, cov neeg nyob hauv qhov hloov pauv tuaj rau hauv kev sib cuag (rau TSIS muaj kev sib cuag) lossis cais (rau NC hu), tso cai lossis cuam tshuam qhov ntws ntawm hluav taws xob tam sim no.Thaum tso tawm tus actuator, lub caij nplooj ntoos hlav mechanism rov qab hloov mus rau nws txoj haujlwm qub, rov qab pib lub xeev ntawm cov neeg sib cuag.
Hom Pushbutton Switches
Pushbutton keyboards tuaj yeem muab faib ua ob hom raws li lawv txoj haujlwm:
1. Momentary:Momentary pushbutton keyboardstsuas yog tswj kev sib txuas ntawm cov neeg sib cuag thaum lub actuator raug nias.Thaum tus actuator raug tso tawm, qhov hloov mus rau nws qhov qub.Piv txwv ntawm cov keyboards lub sijhawm muaj xws li cov keyboards hauv computer, doorbells, thiab game controllers.
2. Latching:Latching pushbutton keyboardstswj lawv lub xeev txawm tias tom qab lub actuator tso tawm.Nias lub actuator ib zaug hloov lub xeev ntawm kev hloov, thiab nias nws rov qab hloov mus rau nws thawj lub xeev.Piv txwv ntawm latching keyboards suav nrog cov khawm fais fab ntawm cov khoom siv hluav taws xob thiab cov keyboards toggle.
Kev siv ntawm Pushbutton Switches
Pushbutton keyboards pom siv ntau yam kev lag luam thiab kev siv, suav nrog:
1. Cov khoom siv hluav taws xob siv hluav taws xob: Cov khoom siv xws li cov chaw taws teeb tswj, cov xov tooj smartphones, thiab cov gaming consoles siv lub pob khawm hloov los pab cov neeg siv tswv yim thiab tswj ntau yam haujlwm.
2. Cov cuab yeej siv: Hauv kev tsim thiab ua cov nroj tsuag, cov keyboards pushbutton feem ntau yog siv los ua ib feem ntawm cov tswj vaj huam sib luag los khiav cov tshuab thiab khoom siv.
3. Cov khoom siv kho mob: Pushbutton keyboards ua lub luag haujlwm tseem ceeb hauv kev tswj cov khoom siv kho mob, xws li cov twj tso kua mis, cov neeg saib xyuas neeg mob, thiab cov cuab yeej kuaj mob.
4. Automotive: Lub tsheb thiab lwm lub tsheb siv lub laub khawm hloov rau kev ua haujlwm xws li pib lub cav, qhib lub teeb, thiab tswj lub suab.
5. Aerospace thiab tiv thaiv: Pushbutton keyboards yog ib qho tseem ceeb hauv kev tswj cov tshuab rau aircraft, spacecraft, thiab cov khoom siv tub rog.
Xaus
Pushbutton keyboards yog ntau yam thiab txhim khu kev qha electromechanical Cheebtsam uas pab tswj cov hluav taws xob circuits nyob rau hauv ib tug dav array ntawm daim ntawv thov.Nkag siab txog lawv txoj haujlwm yooj yim thiab ntau hom muaj pub rau cov neeg tsim qauv thiab cov kws tsim qauv xaiv cov kev hloov uas tsim nyog tshaj plaws rau lawv cov kev xav tau tshwj xeeb.Raws li kev siv thev naus laus zis txuas ntxiv mus, cov keyboards khawm yuav tseem yog ib feem tseem ceeb ntawm peb lub neej niaj hnub, muab peb txoj hauv kev yooj yim thiab siv tau zoo los cuam tshuam nrog cov khoom siv nyob ib puag ncig peb.
