Cov yam ntxwv ntawm Push Button Switch

Push khawm keyboards yog qhov yooj yim tab sis ua haujlwm tau zoo heev uas tuaj yeem siv rau ntau yam kev siv. Lawv tuaj yeem pom hauv cov khoom siv hauv tsev, cov khoom siv hluav taws xob, thiab txawm tias muaj cov tshuab ua haujlwm. Cov keyboards no feem ntau yog siv los qhib thiab tawm ntawm lub cuab yeej lossis los ua kom ua haujlwm. Push khawm keyboards tuaj nrog cov yam ntxwv sib txawv, uas tso cai rau cov neeg siv kho thiab kho lawv cov haujlwm raws li lawv xav tau. Hauv tsab xov xwm no, peb yuav tshawb txog cov yam ntxwv ntawm lub laub khawm keyboards.

1. Hloov kev xaiv

Push khawm keyboards tuaj nrog cov kev xaiv sib txawv nyob ntawm daim ntawv thov. Hom kev hloov pauv ntau tshaj plaws yog ib leeg-ncej ib leeg-tso (SPST), uas tsuas muaj ib qho kev sib cuag. Hom kev hloov no yog tsim rau kev siv yooj yim rau / tawm. Lwm hom yog ib leeg-ncej ob-txheej (SPDT) hloov, uas muaj ob qhov kev sib cuag uas txuas nrog ib qho ntawm ob lub voj voog. Hom kev hloov no muaj txiaj ntsig zoo thaum xav tau hloov ntawm ob lub voj voog. Qhov ob-ncej ob-tho (DPDT) hloov pauv muaj ob pawg sib txuas uas tuaj yeem txuas rau ob qhov sib txawv. Qhov kev hloov no muaj txiaj ntsig zoo thaum xav tau hloov ntawm ob lub voj voog.

2. Illuminated Switches

Illuminated laub khawm keyboards muaj ib lub teeb built-in uas qhia txog qhov hloov pauv. Cov keyboards no tsim nyog rau cov ntawv thov uas qhov hloov qhov xwm txheej yuav tsum tau pom nyob rau hauv cov teeb pom kev tsis zoo. Illuminated laub khawm keyboards tuaj nrog cov xim sib txawv, suav nrog liab, ntsuab, daj, thiab xiav. Lub teeb tuaj yeem ruaj khov lossis flashing, nyob ntawm daim ntawv thov.

3. Momentary lossis Latching Push Buttons

Push khawm keyboards tuaj yeem ua ib ntus lossis latching. Momentary laub khawm keyboards yog tsim los nias thiab tso tawm sai sai, thiab lawv rov qab mus rau lawv qhov qub qub thaum tso tawm. Cov keyboards no tsim nyog rau cov ntawv thov uas yuav tsum tau hloov lub sijhawm luv luv los qhib qhov tshwj xeeb. Latching laub khawm keyboards, ntawm qhov tod tes, nyob twj ywm hauv lawv txoj haujlwm kawg kom txog thaum lawv rov pib dua. Cov keyboards no tsim nyog rau cov ntawv thov uas qhov hloov pauv yuav tsum nyob hauv txoj haujlwm qhib lossis tawm rau lub sijhawm ntev dua.

4. Tamper-Proof Switches

Tamper-pov thawj laub khawm keyboards yog tsim los tiv thaiv kev nkag mus tsis tau kev tso cai los yog ua kom yuam kev. Cov keyboards no feem ntau siv nyob rau hauv kev lag luam chaw, qhov twg cov cav tov thiab cov cuab yeej yuav tsum tau muab kaw kom tsis txhob muaj kev tso cai nkag los yog siv. Lawv kuj tau siv rau hauv kev tswj hwm kev tswj hwm los tiv thaiv cov neeg tsis tau tso cai los ntawm kev nkag mus rau hauv cov chaw txwv.

5. Weatherproof thiab Water-Resistant Switches

Push khawm keyboards tuaj yeem tsim los ua huab cua tsis zoo lossis dej-resistant. Lub khawm hloov pauv huab cua tsis zoo yog tsim los tiv thaiv cov av noo, plua plav, thiab lwm yam ib puag ncig uas tuaj yeem cuam tshuam rau nws txoj haujlwm. Lub laub khawm hloov dej yog tsim los tiv thaiv cov dej nkag thiab tuaj yeem siv rau hauv cov ntawv thov uas qhov hloov pauv yuav raug rau dej lossis lwm yam dej.

6. Qhov ntau thiab tsawg thiab cov duab sib txawv

Push khawm keyboards tuaj ntau qhov sib txawv thiab cov duab, nyob ntawm daim ntawv thov. Lawv tuaj yeem yog cylindrical, square, rectangular, lossis txawm oval-puab. Qhov loj ntawm qhov hloov pauv kuj txawv, los ntawm cov hloov me me uas tuaj yeem haum rau ntawm PCB mus rau cov keyboards loj dua uas tuaj yeem txuas rau ntawm lub vaj huam sib luag.

7. Ntau hom Mounting

Push khawm keyboards tuaj yeem txuas rau ntau txoj hauv kev, nyob ntawm daim ntawv thov. Feem ntau hom mounting yog nto-mounted thiab vaj huam sib luag-mounted keyboards. Nto-mounted keyboards yog txuas rau saum npoo ntawm PCB, thaum lub vaj huam sib luag-mounted keyboards yog mounted rau ntawm ib lub vaj huam sib luag los yog enclosure siv ib tug threaded dab tshos los yog ib tug snap-in mechanism.

Xaus

Hauv cov ntsiab lus, lub laub khawm keyboards tuaj nrog ntau yam nta uas ua rau lawv haum rau kev siv sib txawv. Cov yam ntxwv no suav nrog cov kev xaiv hloov pauv, lub teeb pom kev hloov pauv, lub sijhawm luv lossis latching laub khawm, tamper-proof keyboards, weatherproof thiab dej-resistant keyboards, ntau qhov sib txawv, thiab cov duab, thiab ntau hom mounting. Thaum xaiv lub laub khawm hloov, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov kom ntseeg tau tias kev ua tau zoo thiab kav ntev.
