Kukankhira pawiri batani Sinthani yotsika mtengo yotsika mtengo ya LED auto kubwerera

Kodi mumadziwa kuti mutha kuwongolera kuchuluka kwa mphamvu zomwe zimayenda kudzera pa switch?Ngati simukudziwa masiwichi awiri-pole, double-throw (DPDT), mwina simukudziwa njira zonse zomwe zingathandize.Zosinthazi zimakhala ndi zolinga ziwiri, zomwe zimapatsa wogwiritsa ntchito mitengo iwiri yosiyana ndi maponyedwe awiri osiyana pamitengo iliyonse.

Amagwiritsidwa ntchito kuthyola kapena kumaliza gawo lamagetsi poyatsa kapena kuzimitsa mabwalo awiri osiyana mkati mwa chipangizo chimodzi.Amagwiritsidwa ntchito kwambiri pantchito zolemetsa monga makina akumafakitale, zida zapakhomo (monga nyali), ndi ma robotiki.Tiyeni tiwone zonse zomwe muyenera kudziwa zokhudza kusintha kwa DPDT patsamba lino.

Chosinthira chapawiri, choponya kawiri (DP-DT) ndi chosinthira chamagetsi wamba chomwe chimalola kuwongolera mabwalo awiri osiyana ndi switch imodzi.Kuchokera ku dzinali, zikutanthauza kuti kusinthaku kuli ndi zolowetsa ziwiri ndi zotulutsa zinayi.Kulowetsa kumodzi kumawongolera zotuluka ziwiri motero amatchedwa kuponyera kawiri.

Kulumikizana kotereku kumatanthauza kuti kusinthaku kumakupatsani mwayi wowongolera kudera linalake kutengera mphamvu yake.Izi zimatheka ndi sliding bar kapena lever yomwe imasuntha kuchokera ku gulu limodzi kupita ku lina, kuyatsa kapena kuzimitsa magetsi.Zomwe zimagwiritsidwa ntchito pakusintha kwa DPDT zimaphatikizapo kuyatsa, kuwongolera magalimoto, ndi kuwongolera mphamvu.

Zosintha zapawiri zapawiri nthawi zambiri zimakhala ndi ma seti awiri odziyimira pawokha pa mbale ziwiri zokhala ndi ma terminals anayi.Seti iliyonse imalumikizidwa ndi mlongoti wake, chifukwa chake amatchedwa dothi lawiri.Mkati mwa mtengo uliwonse, pali zolumikizira ziwiri zomwe zitha kuponyedwa paokha kuti zilole kuyenda kwanthawi zonse mbali iliyonse.

Momwe zimagwirira ntchito ndizosavuta: zapano zimalowa mumtengo umodzi ndikudutsa pagulu loyamba la zolumikizirana zomwe zimadutsa gawo lachiwiri la zolumikizirana kenako ndikulowa mumtengo wina.

Pa chipangizo chokhala ndi cholowetsa chimodzi chokha, mutha kugwiritsa ntchito switch iyi kuyatsa/kuzimitsa china chake kapena kusintha polarity yake.Ngati muli ndi peyala yopitilira imodzi, muli ndi zosankha zambiri.

Mutha kulumikiza awiriawiri ambiri palimodzi kuti onse agawane cholowetsa chimodzi koma ali ndi zotulutsa zawo komanso njira zawo zowongolera (monga chosinthira chowunikira).
