Iiswitshi zokucofa iqhoshazizinto ezibalulekileyo kwizixhobo ze-elektroniki zanamhlanje, nto leyo evumela abasebenzisi ukuba basebenzisane nezixhobo ngaphandle kokuphazamiseka. Nangona kunjalo, ukuphonononga ummandla weeswitshi zeqhosha lokucinezela kunokungenisa amagama anjengelithi "NC" kunye nelithi "NO," anokubonakala edida ekuqaleni. Masisuse olu kudideka size siqonde ngokucacileyo ukubaluleka kwawo.
'NC' - Ivalwe Ngokwesiqhelo: Kwimeko yeswitshi yeqhosha lokucinezela, 'NC' imele "Ivalwe Ngokwesiqhelo." Oku kubonisa imeko emiselweyo yee-contacts zeswitshi xa iqhosha lingachukunyiswanga. Kule meko, isekethe ephakathi kwee-terminals ze-'NC' igqityiwe, ivumela ukuhamba kombane. Xa ucinezela iqhosha, isekethe iyavuleka, iphazamise ukuhamba kombane.
'HAYI' - Ngokwesiqhelo Vula: 'HAYI' imele "Vula Ngokwesiqhelo," nto leyo ebonisa imeko yee-contacts zeswitshi xa iqhosha lingacinezelwanga. Kule meko, isekethe ethi 'HAYI' ihlala ivuliwe ngokuzenzekelayo. Ukucinezela iqhosha kuqalisa ukuvalwa kwesekethe, okuvumela ukuba umbane udlule kwiswitshi.
Ukuqonda iindima zoqwalaselo lwe-'NC' kunye ne-'NO' kubalulekile ekukhetheni iswitshi yeqhosha lokucofa elifanelekileyo kwizicelo ezithile, nokuba zibandakanya amanyathelo okhuseleko okanye imisebenzi yolawulo kwiinkqubo ze-elektroniki.
Ngaphaya Kwezinto Ezisisiseko: Ezinye Izinto Omele Uziqwalasele
Xa ukhetha phakathi koqhagamshelwano lwe-NC kunye no-NO, kubalulekile nokuqwalasela uhlobo lomsebenzi oluza kwenziwa yiswitshi. Umzekelo, oonxibelelwano be-NC badla ngokusetyenziswa kwimisebenzi yokumisa ngokukhawuleza kuba isekethe iyaphuka ngoko nangoko xa iqhosha licinezelwe, okuqinisekisa ukuvalwa ngokukhawuleza ngenxa yokhuseleko. Ngokwahlukileyo koko, oonxibelelwano be-NO bafanelekile kwimisebenzi yokuvula, njengokunika amandla izixhobo okanye ukwenza izenzo ezithile kuphela xa iqhosha licinezelwe.
Ngaphezu koko, iiswitshi ezininzi zanamhlanje zeqhosha lokucinezela zibonelela ngoqwalaselo lonxibelelwano oluninzi, oluvumela zombini iiterminal ze-NC kunye ne-NO kumzimba omnye weswitshi. Oku kwenza abayili bakwazi ukudala iinkqubo zolawulo eziguquguqukayo nezingafunekiyo, ezisetyenziswa kakhulu kwi-automation yemizi-mveliso, iiphaneli ze-elevator, kunye nezikhululo zolawulo loomatshini.
Enye into ebalulekileyo kukuqina kwendalo kweswitshi. Ngokuxhomekeke kwisicelo, unokufuna iimpawu ezifana novavanyo lokungena kwamanzi lwe-IP65 okanye i-IP67, ukumelana nempembelelo, okanye iziqinisekiso ze-UL/CE ukuqinisekisa ukuthembeka kwexesha elide. Iindlela zokukhanyisa—ezifana nezibane zendandatho ze-LED—nazo zidlala indima ebalulekileyo ekubonakaleni namava omsebenzisi, ingakumbi kwiindawo ezinokukhanya okuphantsi okanye kwiindawo zoshishino.
Ekugqibeleni, oonxibelelwano be-NC kunye no-NO bakha isiseko sendlela esebenza ngayo iiswitshi zeqhosha lokucofa, kodwa ukuqonda iimpawu zazo ezinde kunye neemeko zesicelo kuya kukunceda ukhethe isisombululo esisebenzayo nesikhuselekileyo kwizixhobo zakho.
Indlela yokukhetha iswitshi yeqhosha le-NC okanye le-NO kwisicelo sakho
Xa ukhetha iswitshi yokucofa iqhosha kwizixhobo zoshishino okanye zorhwebo, ukuqonda iintlobo zoqhagamshelwano ze-NC kunye ne-NO yinyathelo lokuqala kuphela. Iinjineli kunye nabathengi kufuneka bahlole indlela iswitshi eza kusetyenziswa ngayo kwinkqubo iyonke. Izinto ezibalulekileyo ekufuneka ziqwalaselwe ziquka imvamisa yokusebenza, uhlobo lomthwalo (i-AC okanye i-DC), imeko yokufakela, kunye neemfuno zokuthobela umthetho.
Kwiinkqubo ezibalulekileyo zokhuseleko ezifana neesekethe zokumisa ezingxamisekileyo, oonxibelelwano be-NC badla ngokukhethwa kuba naluphi na uphazamiseko—nokuba lubangelwa kukucinezela iqhosha okanye kukusilela kwentambo—luya kuyimisa ngoko nangoko izixhobo. Ngokwahlukileyo koko, AKUKHO oonxibelelwano badla ngokusetyenziswa kwimisebenzi yokuqalisa, yokuseta kwakhona, kunye neyokuvula, apho isekethe kufuneka ivale kuphela xa umsebenzisi efaka ngabom.
Ukongeza, izinto ezifana nendlela yokufaka (iphaneli yokufaka okanye i-PCB mount), isitayile sesiphelo (isikrufu, i-solder, okanye i-quick-connect), kunye neendlela zokukhanyisa zinokuchaphazela ukusebenza kakuhle kofakelo kunye namava omsebenzisi. Ukukhetha iswitshi yeqhosha elicofayo elihambelana neenkcukacha zakho zombane, iimeko zokusingqongileyo, kunye neenjongo zokusebenza kunceda ukuqinisekisa ukuthembeka kwexesha elide ngelixa kunciphisa ukugcinwa kunye nexesha lokungasebenzi.
Kwii-OEM kunye nabahlanganisi beenkqubo, ukusebenzisana nomvelisi othembekileyo wokutshintsha amaqhosha acinezelayo obonelela ngomgangatho ohambelanayo, inkxaso yokwenza ngokwezifiso, kunye neziqinisekiso zokuthobela imithetho yehlabathi kunokwenza lula ukuthengwa kwempahla kunye nokunciphisa iingozi zeprojekthi.
