Push khawm keyboards nrog built-in LEDs muab txoj hauv kev ua tau zoo thiab pom kev zoo los ua haujlwm hauv cov khoom siv hluav taws xob, muab ob qho tib si tswj thiab qhia hauv ib feem.Lawv feem ntau siv rau hauv daim ntawv thov tsheb, tsev automation systems, thiab industrial control panels.Hauv tsab xov xwm no, peb yuav taug kev koj los ntawm cov txheej txheem ntawm kev xaim a12V laub khawm hloovnrog lub LED, coj koj los ntawm cov kauj ruam tsim nyog, cov khoom, thiab kev ceev faj txog kev nyab xeeb.
Nkag siab txog cov Cheebtsam
Ua ntej dhia mus rau hauv cov txheej txheem xaim, cia peb paub peb tus kheej nrog cov ntsiab lus tseem ceeb:
1. 12V Push Button Hloov nrog LED: Cov keyboards no muaj ib qho kev sib xyaw ua ke uas ua rau lub teeb ci thaum lub tshuab ua haujlwm.Lawv feem ntau muaj peb lossis plaub lub davhlau ya nyob twg: ib qho rau cov khoom siv hluav taws xob (zoo), ib qho rau hauv av (tsis zoo), ib qho rau cov khoom thauj (device), thiab qee zaum muaj qhov txuas ntxiv rau hauv av LED.
2. Lub Hwj Chim Loj: Ib qho 12V DC fais fab mov, xws li lub roj teeb lossis lub hwj huam mov, yog xav tau los muab lub zog rau qhov hloov pauv thiab cov cuab yeej txuas nrog.
3. Load (Device): Cov cuab yeej koj xav tswj nrog lub laub khawm hloov, xws li lub cev muaj zog, lub teeb, lossis kiv cua.
4. Hlau: Koj yuav xav tau cov hlau loj kom tsim nyog los txuas rau ntau yam khoom.Rau feem ntau 12V daim ntawv thov, 18-22 AWG hlau yuav tsum txaus.
5. Inline Fuse (yeem, tab sis pom zoo): Ib qho inline fuse tuaj yeem ntsia tau los tiv thaiv Circuit Court los ntawm luv circuits lossis overcurrent tej yam kev mob.
Txuas lub 12V Push Button Hloov nrog LED
Ua raws li cov kauj ruam no kom xaim 12V laub khawm hloov nrog LED:
1. Tshem tawm lub hwj chim: Ua ntej pib cov txheej txheem xaim, xyuas kom lub 12V fais fab tuag los yog txiav tawm kom tsis txhob muaj kev sib tsoo luv luv lossis hluav taws xob poob.
2. Txheeb xyuas cov terminals: Tshawb xyuas lub laub khawm hloov txhawm rau txheeb xyuas cov terminals.Lawv feem ntau sau npe, tab sis yog tias tsis yog, xa mus rau cov chaw tsim khoom cov ntaub ntawv lossis cov ntaub ntawv cov khoom.Cov ntawv dav dav dav suav nrog "+" rau lub zog nkag, "GND" lossis "-" rau hauv av, "LOAD" lossis "OUT" rau lub cuab yeej, thiab "LED GND" rau hauv av LED (yog tias muaj).
3. Txuas lub zog hluav taws xob: Siv cov xaim tsim nyog, txuas lub davhlau ya nyob twg zoo ntawm lub zog hluav taws xob mus rau lub tshuab hluav taws xob input ("+") ntawm lub laub khawm hloov.Yog tias koj siv lub fuse inline, txuas nws ntawm lub zog hluav taws xob thiab qhov hloov.
4. Txuas hauv av: Txuas lub davhlau ya nyob twg tsis zoo ntawm lub zog hluav taws xob mus rau hauv av davhlau ya nyob twg ("GND" lossis "-") ntawm lub laub khawm hloov.Yog tias koj qhov hloov pauv muaj qhov sib cais LED hauv av, txuas rau hauv av thiab.
5. Txuas lub load (kwv yees): Txuas lub davhlau ya nyob twg ("LOAD" lossis "OUT") ntawm lub laub khawm hloov mus rau qhov zoo ntawm lub davhlau ya nyob twg koj xav tswj.
6. Ua kom tiav lub voj voog: Txuas lub davhlau ya nyob twg tsis zoo ntawm lub cuab yeej mus rau hauv av, ua kom tiav lub voj voog.Rau qee cov khoom siv, qhov no yuav cuam tshuam ncaj qha mus rau qhov tsis zoo ntawm lub zog hluav taws xob lossis mus rau hauv av davhlau ya nyob twg ntawm lub laub khawm hloov.
7. Kuaj qhov teeb tsa: Qhib lub hwj chim thiabnias lub khawmhloov.LED yuav tsum teeb, thiab cov khoom siv txuas nrog yuav tsum ua haujlwm.Yog tias tsis yog, xyuas ob zaug koj cov kev sib txuas thiab xyuas kom meej tias tag nrho cov khoom ua haujlwm raug.
Kev Tiv Thaiv Kev Nyab Xeeb
Thaum ua hauj lwm nrog hluav taws xob thaiv, nco ntsoov ua raws li cov kev ceev faj txog kev nyab xeeb:
1. Tshem tawm lub hwj chim: Ib txwm txiav lub hwj chim qhov chaw ua ntej yuav ua hauj lwm ntawm tej yam thaiv kom tsis txhob raug hluav taws xob shocks los yog luv luv circuits.
2. Siv cov hlau loj uas tsim nyog: Xaiv cov hlau loj uas tuaj yeem ua raws li qhov yuav tsum tau muaj tam sim no ntawm koj daim ntawv thov tshwj xeeb kom tsis txhob muaj cua sov lossis qhov hluav taws xob poob.
3. Kev sib txuas ruaj ntseg: xyuas kom txhua qhov kev sib txuas tau ruaj ntseg zoo, siv cov khoom sib txuas, cov hlua khi, lossis cov khoom siv davhlau ya nyob twg, txhawm rau tiv thaiv kev sib tsoo los yog luv luv.
4. Insulate raug xov hlau: Siv cov cua sov shrink tubing los yog hluav taws xob daim kab xev los npog cov xov hlau sib txuas, txo qhov kev pheej hmoo ntawm hluav taws xob shocks thiab luv Circuit Court.
5. Nruab ib lub fuse inline: Thaum xaiv tau, ib qho inline fuse tuaj yeem pab tiv thaiv koj lub voj voog ntawm luv luv Circuit Court lossis overcurrent tej yam kev mob, tiv thaiv kev puas tsuaj rau cov khoom siv lossis txuas.
6. Khaws cov hlua khi kom ruaj khov: Siv cov hlua khi, cov hlua khi, lossis lub tes tsho cable kom cov hlua khi kom ruaj khov thiab huv si, txo cov kev pheej hmoo ntawm cov xov hlau los yog puas.
7. Ua tib zoo sim: Thaum kuaj koj qhov teeb tsa, ceev faj thiab npaj tua hluav taws xob tam sim yog tias koj pom muaj teeb meem, xws li sparks, pa taws, lossis kev coj cwj pwm txawv txav.
