Ib tus ncej ib qho kev hloov pauv hloov, tseem hu ua SPST hloov, yog ib hom kev hloov pauv uas siv hauv hluav taws xob circuits. Nws yog qhov yooj yim rau / tawm hloov pauv uas tswj tau ib lub voj voog ib zaug, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau ib qho kev tswj kom tig lub cuab yeej rau lossis tawm.
SPST keyboards tuaj nyob rau hauv ntau qhov ntau thiab tsawg, los ntawm cov keyboards me me siv hauv cov khoom siv hluav taws xob mus rau cov keyboards loj dua siv hauv kev lag luam. Lawv kuj muaj nyob rau hauv ntau qhov sib txawv configurations, nrog ntau hom terminals thiab mounting xaiv.
Kev ua haujlwm yooj yim ntawm kev hloov SPST yog qhov yooj yim heev. Thaum qhov hloov pauv nyob rau hauv txoj haujlwm 'on', cov neeg raug kaw thiab tam sim no tuaj yeem dhau los ntawm kev hloov. Thaum qhov hloov pauv nyob rau hauv txoj haujlwm 'tawm', cov neeg sib cuag tau qhib thiab tsis muaj tam sim no tuaj yeem ntws.
Txoj hauv kev zoo tshaj plaws los siv SPST hloov yog xaim nws hauv cov khoom siv, xws li lub teeb, lub cev muaj zog lossis lub zog. Qhov no tso cai rau tus neeg siv tig lub cuab yeej rau lossis tawm nrog qhov yooj yim flip ntawm qhov hloov.
SPST keyboards kuj tseem siv tau nyob rau hauv ntau lub circuits, uas lawv siv los tswj lub on / off lub xeev ntawm ib tug transistor los yog relay, uas nyob rau hauv lem tswj cov ntws ntawm tam sim no mus rau lwm yam khoom siv nyob rau hauv lub Circuit Court.
Ib qho kev txiav txim siab tseem ceeb thaum xaiv qhov hloov SPST yog tus nqi tam sim no uas yuav ntws los ntawm kev hloov. Yog tias qhov hloov pauv tau ntsuas rau qis dua tam sim no tshaj li lub cuab yeej nws tswj, nws yuav dhau los ua kom sov thiab ua tsis tiav. Nws yog ib qho tseem ceeb uas yuav tau xaiv ib qho kev hloov nrog qhov ntsuas uas tsim nyog rau cov cuab yeej uas nws yuav tswj tau.
Lwm qhov kev txiav txim siab thaum xaiv qhov hloov SPST yog hom terminals uas nws muaj. Cov keyboards nrog solder terminals yog cov feem ntau, tab sis cov keyboards nrog cov ntsia hlau terminals los yog ceev-txuas terminals kuj muaj. Txoj kev mounting kuj tseem ceeb heev uas yuav tsum tau xav txog, vim qee qhov hloov pauv tau tsim los rau kev teeb tsa vaj huam sib luag thiab lwm tus yog tsim los rau PCB mounting.
Hauv cov ntsiab lus, ib tus ncej ib qho kev cuam tshuam ib leeg yog qhov hloov pauv yooj yim thiab txhim khu kev qha uas yog qhov zoo tagnrho rau ntau lub tshuab hluav taws xob. Nws yog ib qho yooj yim mus use, yooj yim rau xaim, thiab muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab configurations. Thaum xaiv qhov hloov pauv SPST, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov ntsuas tam sim no, hom davhlau ya nyob twg, thiab txoj hauv kev txuas kom ntseeg tau tias qhov hloov pauv yuav ua haujlwm raug hauv daim ntawv thov.
