Usenokuba ubonile ukutshintshwa okuncinci kwiindidi ezahlukeneyo zezixhobo, kodwa ngekhe ulazi igama elipheleleyo lale mveliso. Igama elithi switch encinci libhekisa kutshintsho oluncinci lwentshukumo. Igama linikwe ngenxa yokuba olu hlobo lweswitshi lufuna inani elincinci lamandla ukuze lusebenze. Kule nqaku, siza kujonga ngakumbi kwimvelaphi yezi yunithi. Funda ukuze ufumane okungakumbi.

Okokuqala, kubalulekile ukugcina engqondweni ukuba ezi yunithi zinokufumaneka kwizixhobo ezininzi, ezinje ngezixhobo kunye neesekethe zombane. Kuba ezi mveliso azidingi mzamo mkhulu ukuze zisebenze, zinokuba lukhetho olukhulu koomatshini, izixhobo zeshishini, ioyile yemicrowave, kunye neelifti ukubiza nje ezimbalwa. Ngaphandle kwalokhu, zinokusetyenziswa kwizithuthi ezininzi. Ngapha koko, asinakulibala inani lezixhobo ze-elektroniki ezisetyenzisiweyo kuzo.

Imvelaphi

Ngokubhekisele kwimvelaphi yezi mveliso, zaziswa ixesha elide emva kokuvela kwezinye iintlobo zeeyunithi ezenza umsebenzi ofanayo. Ngethuba lokuqala, utshintsho oluncinci lwenziwa ngo-1932 yingcali egama linguPeter McGall.

Kumashumi ambalwa eminyaka kamva, uHoneywell Sensing kunye noLawulo bayithengile inkampani. Nangona uphawu lwentengiso lusengolukaHoneywell, uninzi lwabanye abenzi benza utshintsho oluncinci olwabelana ngolwakhiwo olufanayo.

Basebenza njani?

Ngenxa yoyilo lwezi yunithi, banokuvula kwaye bavale isekethe ye-elektroniki ngephanyazo. Nokuba kusetyenziswa isixa esincinci soxinzelelo, isekethe inokuqhubeka nokucima ngokusekwe kulwakhiwo kunye nofakelo lweswitshi.

Iswitshi inenkqubo yasentwasahlobo ngaphakathi kuyo. Iyaqala ngenxa yentshukumo ye-lever, iqhosha-iqhosha, okanye i-roller. Xa uxinzelelo oluncinci lusetyenziswa ngoncedo lwentwasahlobo, isenzo se-snap senzeka ngaphakathi kotshintsho ngomzuzwana. Ke, ungatsho ukuba ukusebenza kwezi yunithi kulula kodwa kubaluleke kakhulu.

Xa le ntshukumo isenzeka, umtya wangaphakathi weyunithi uvelisa isandi sokucofa. Ungahlengahlengisa amandla angaphandle anokuvula utshintsho. Ngamanye amagama, unokuthatha isigqibo malunga nokuba uxinzelelo olungakanani ekufuneka lusetyenzisiwe ukwenza utshintsho lusebenze.

Nangona olu tshintsho lincinci luyilo olulula, yimpendulo ekhawulezileyo yeyunithi eyenza ukuba ibe lukhetho olufanelekileyo kwizicelo ezahlukeneyo apha nakwangoku. Ke ngoko, ezi mveliso zithathe indawo yezinye iimveliso ezininzi ezazisiwe ngaphambili. Ke, ndinokuthi ezi tshintshi ziqhuba izangqa zijikeleze ezinye iiyunithi ezininzi onokuzifumana kwimarike.

Ke, esi yayisisingeniso sendlela ezisebenza ngayo ezi microswitches kunye nento onokuyilindela kubo. Ukuba ufuna ukufumana okuninzi kubo, sicebisa ukuba ubathenge kwinkampani elungileyo. Emva kwayo yonke loo nto, awufuni ukuphela ngeyunithi engalunganga. Ke ngoko, ukukhetha eyona yunithi ilungileyo kukubetha kwengqondo.
