Ndingayikhetha njaniiqhosha lokucofa？Ungakwazi ngokuchanekileyoQhagamshelana nathi, singakunika isisombululo esifanelekileyo.
Ngokuqinisekileyo, nazi ezinye iindlela ezilula onokuzisebenzisa ukuze ubhale ngazo.
1. Injongo kunye nokusetyenziswa
Qala ngokuqonda injongo kunye nokusetyenziswa kweswitshi yeqhosha lokucofa. Iiswitshi ezahlukeneyo zenzelwe imisebenzi eyahlukeneyo, njengezenzo zesikhashana okanye zokuncamathela. Qinisekisa ukuba iswitshi iya kusetyenziselwa ulawulo lwamandla, ukusebenza kwesignali, okanye eminye imisebenzi ethile.
2. Uhlobo Lokusebenza
Iiswitshi zeqhosha lokucinezela zingahlulwahlulwa zibe ziintlobo zexeshana kunye neentlobo zokuncamathela. Iiswitshi zexeshana zibuyela kwimeko yazo yokuqala xa zikhululwa, ngelixa iiswitshi zokuncamathela zihlala kwindawo yokuvula/yokucima de zitshintshwe ngesandla. Khetha uhlobo oluhambelana kakuhle neemfuno zesixhobo sakho.
3. Uqwalaselo loQhagamshelwano
Uqwalaselo loqhagamshelwano lubhekisa kwinani lee-contacts zombane kwiswitshi. Uqwalaselo oluqhelekileyo luquka i-single-pole single-throw (SPST) kunye ne-double-pole double-throw (DPDT). Cinga ukuba zingaphi iisekethe iswitshi efunekayo ukulawula kwaye ukhethe uqwalaselo loqhagamshelwano olufanelekileyo.
4. Ubungakanani kunye nokuFakelwa
Ubungakanani obubonakalayo kunye nendlela yokuyifaka iswitshi kubalulekile ekudityanisweni kwesixhobo sakho. Khetha iswitshi elingana kakuhle kwindawo ekhoyo kwaye inokufakelwa ngokulula usebenzisa izikrufu, iindlela zokungena, okanye ezinye iindlela ezifanelekileyo.
5. Uyilo lwe-Actuator
I-actuator yinxalenye yeswitshi ecinezelwa ngabasebenzisi. Iza ngeemilo ezahlukeneyo, ubukhulu, kunye nemibala. Khetha uyilo lwe-actuator oluhambelanayo noluhambelana nokukhetha komsebenzisi ukusebenzisana. Cinga ngezinto ezifana nokuma kwamaqhosha, ubungakanani, kunye nempendulo echukumisekayo.
6. Uvavanyo loMbane
Qinisekisa ukuba umlinganiselo wombane weswitshi uyahambelana neemfuno zesixhobo sakho. Oku kuquka izinto ezinje ngomlinganiselo wombane kunye nomlinganiselo wamandla. Ukukhetha iswitshi enomlinganiselo wombane ofanelekileyo kuthintela ukugqithisa kakhulu kwaye kuqinisekisa ukhuseleko.
7. Iimeko zeNdalo
Cinga ngemeko yokusebenza kwesixhobo sakho. Ukuba siza kusetyenziswa ngaphandle okanye kwiimeko ezinzima, khetha iswitshi yeqhosha elicinezelweyo elinokuvala okufanelekileyo kunye nokukhusela uthuli, amanzi, nezinye izinto.
8. Ubude bexesha elide kunye nokuqina
Umgangatho ubalulekile xa kufikwa kwiiswitshi zokucofa amaqhosha. Khangela iiswitshi ezivela kubavelisi abaziwayo ngokuvelisa izinto ezihlala ixesha elide nezihlala ixesha elide. Oku kunceda ukuthintela ukungasebenzi kakuhle kwangethuba kwaye kuqinisekisa amava omsebenzisi athembekileyo.
9. Ubuhle Bobuhle
Nangona ukusebenza kwayo kubalulekile, imbonakalo yayo ayifanele ijongwe, ingakumbi kwiimveliso ezijongene nabathengi. Khetha iswitshi ehambelana noyilo olupheleleyo kunye nobuhle besixhobo sakho.
10. Ukuthobela imithetho kunye neziqinisekiso
Ukuba isixhobo sakho sifuna ukuhlangabezana nemigangatho okanye imigaqo ethile yoshishino, qinisekisa ukuba iswitshi yeqhosha lokucinezela ekhethiweyo ihambelana neziqinisekiso ezifunekayo, ezifana ne-UL, i-CE, okanye i-RoHS.
Ukuqukumbela, ukukhetha iswitshi yeqhosha lokutyhala kubandakanya ukuqwalasela izinto ezifana nenjongo yeswitshi, uhlobo lokusebenza, uqwalaselo loqhagamshelwano, ubungakanani, uyilo lwe-actuator, umlinganiselo wombane, iimeko zokusingqongileyo, ukuqina, ubuhle, kunye nokuthobela. Ngokuvavanya ngononophelo ezi zinto, ungakhetha iswitshi yeqhosha lokutyhala elifanelekileyo ukuphucula ukusebenza kunye namava omsebenzisi wesixhobo sakho se-elektroniki okanye inkqubo.
