Ib tug relay yog ib electromagnetic hloov ua los ntawm cov hluav taws xob me me uas tuaj yeem qhib lossis tawm hluav taws xob loj dua. Lub plawv ntawm ib tug relay yog ib electromagnet (ib lub kauj ntawm cov hlau uas dhau los ua cov hlau nplaum ib ntus thaum hluav taws xob ntws los ntawm nws).

Dhau li ntawm no, dab tsi yog qhov sib nqus hloov siv rau?

Yooj yim sib nqus keyboards yog siv rau txheeb xyuas qhov qhib qhov rooj thiab qhov rais. Ib qho yooj yim magnetic hloov muaj ob ntu - lub hlau nplaum thiab magnetic rhiab heev hloov (feem ntau yog ib tug reed hloov nyob rau hauv ib lub hnab ntawv iav). Hloov tej zaum yuav yog ib txwm qhib (kaw ntawm lub tswb) lossis ib txwm kaw (qhib ntawm lub tswb).

Qhov thib ob, 12 volt relay ua haujlwm li cas? Feem ntau 12 volt relays ua haujlwm cov khoom siv hauv tsheb thiab lwm yam tsav tsheb. Thaum koj siv me me tam sim no rau lub relay coil, qhov no kaw kev sib cuag uas nyob rau hauv lem pub zog rau ib tug accessory uas ib txwm xav tau ntau tam sim no rau ua haujlwm.

Kuj paub, qhov hloov magnetic ua haujlwm li cas?

Thawj tsim nyob rau hauv 1930s, magnetic keyboards ua haujlwm zoo ib yam li relays, kaw ib qho hluav taws xob tiv tauj nyob rau hauv lub xub ntiag ntawm a Sib nqus teb. Tsis zoo li relays, sib nqus keyboards raug kaw hauv iav. Vim lawv raug kaw, sib nqus keyboards tshem tawm cov teeb meem tshwm sim hauv qhov chaw uas muaj hluav taws kub los yog tawg.

Qhov twg siv electromechanical relays?

Electromechanical relays yog keyboards uas feem ntau yog siv tswj cov khoom siv hluav taws xob muaj zog. Electromechanical relays yog siv nyob rau hauv ntau lub tshuab hluav taws xob niaj hnub no thaum nws tseem ceeb heev rau kev tswj ib lub voj voog, txawm tias muaj lub teeb liab hluav taws xob tsawg lossis thaum ntau lub voj voog yuav tsum tau tswj los ntawm ib lub teeb liab.
