Feem ntau kev sib txuas lus sib txuas tau muab faib ua 4 hom, xws li:
- SPST (Tib ncej Ib leeg pov)
- SPDT (ib tug ncej ob tog pov)
- DPST (ob tug ncej, ib qho pov tseg)
- DPDT (ob tug ncej ob tog pov)
✔SPST (Tib ncej Ib leeg pov)
SPST yog qhov yooj yim tshaj plawsnquag qhib hloovnrog ob lub davhlau ya nyob twg pins, uas feem ntau yog siv los txuas lossis tig thiab tawm tam sim no hauv Circuit Court.CDOE hom feem ntau qhib khawm yog IP65 waterproofGQ series.
Daim ntawv thov ntawm covSPST hloovyog lub teeb hloov tau pom hauv daim duab hauv qab no.Feem ntau, hom kev hloov no muaj qhov tso tawm thiab cov khoom siv tawm tswv yim, thiab tsis paub qhov txawv ntawm lub davhlau ya nyob twg pins.ON/OFF hloov, thaum qhov hloov pauv hauv Circuit Court hauv qab no qhib, tam sim no yuav ntws los ntawm ob lub terminals, thiab lub teeb lossis load hauv Circuit Court yuav pib ua haujlwm.Thaum lub kaw lus kaw, tsis muaj qhov tam sim no ntws los ntawm ob lub terminals.
✔SPDT (ib tug ncej ob tog pov)
SPDT hloov yog peb tus pins davhlau ya nyob twg hloov, ib lub davhlau ya nyob twg yog siv los ua cov tswv yim thiab ob lub davhlau ya nyob twg yog siv los ua cov zis.Cov nyees khawm hlau uas muaj ib qho qhib thiab ib qho kaw yuav muaj: C davhlau ya nyob twg (Common ko taw), NC (Nquag Kaw ko taw), TSIS MUAJ (Nquag qhib ko taw).Nws tuaj yeem txuas nrog ib lossis lwm qhov ntawm ob, thiab cov neeg siv khoom tuaj yeem daws tau raws li qhov xav tau tiag tiag.Lub pob khawm uas peb lub tuam txhab txhawb nqa ib qho qhib thiab ib qho kaw suav nrog (16 hli mounting qhov, 19mm mounting qhov, 22mm mounting qhov, 25mm mounting qhov);S1GQ series (19mm, 22mm, 25mm, 30mm), xb2 / lay5 series ., thiab lwm yam
Daim ntawv thov hloov ntawm ib qho ib txwm qhib thiab ib qho kev kaw ib txwm yog tsim los rau peb lub voj voog, uas yog siv los qhib thiab tawm lub teeb nyob rau sab saud thiab qis ntawm cov ntaiv.Hauv Circuit Court hauv qab no, thaum hloov A qhib, tsuas yog A yuav teeb thiab B yuav tawm mus.Thaum hloov B tau qhib, tsuas yog B yuav teeb thiab lub teeb A yuav tsis ua haujlwm.Ib qho ntawm cov circuits yog tswj cov teeb pom kev zoo los ntawm aSPDT hloov khawm.
✔DPST (ob tug ncej, ib qho pov tseg)
Qhov hloov DPST tseem hu ua aob feem ntau qhib khawm hloov, uas txhais tau hais tias ib qho DPST khawm hloov tswj ob lub voj voog sib cais tib lub sijhawm.Ob lub nyees khawm qhib yuav muaj plaub tus pins davhlau ya nyob twg, ob lub davhlau ya nyob twg, thiab ob lub davhlau ya nyob twg ib txwm qhib.Thaum lub pob khawm no pib ua haujlwm, tam sim no pib ntws los ntawm ob lub voj voog.Thaum lub khawm tsis ua haujlwm, ob lub voj voog tseem yuav nres tib lub sijhawm.
✔DPDT (ob tug ncej ob tog pov)
DPDT hloov yog sib npaug rau muaj ob lub SPDT keyboards, uas yog, ob lub 1no1nc muaj nuj nqi laub khawm hloov, uas txhais tau hais tias muaj ob lub voj voog ywj pheej.Ob lub inputs ntawm txhua lub voj voog txuas nrog rau ob qhov tso zis, qhov hloov chaw tswj cov xov tooj ntawm txoj kev, thiab txhua qhov kev sib cuag tuaj yeem raug xa los ntawm ob qho tib si.
Thaum nws nyob rau hauv ON-ON hom lossis ON-OFF-ON hom lawv ua haujlwm zoo li ob qhov sib cais SPDT keyboards ua haujlwm los ntawm cov actuator zoo sib xws.Nyob rau hauv ib lub sij hawm tsuas yog ob lub loads tuaj yeem ON.Ib qho DPDT hloov tuaj yeem siv tau rau hauv txhua daim ntawv thov uas xav tau qhib thiab kaw cov kab hluav taws xob.
