Ukutshintsha ingcongolo sisilayidi sombane esisetyenziswa yimagnethi esetyenziswayo. Ngelixa isenokujongeka nje njengeqhekeza leglasi elinezikhokelo eziphuma kuyo, sisixhobo esenziwe ngobunjineli esisebenza ngeendlela ezimangalisayo kunye neendlela zokwenza ngokwezifiso ezisetyenziselwe ukusetyenziswa kwazo kwizicelo ezininzi. Phantse zonke iiswitshi zengcongolo zisebenza kwindawo yamandla anomtsalane: ipolarity echaseneyo iphuhla kunxibelelwano oluqhelekileyo oluvulekileyo. Xa i-magnetism yanele, la mandla anqoba ukuqina kweengcongolo zengcongolo, kwaye uqhagamshelwano ludibanisa.
Le ngcamango yaqalwa ngo-1922 ngunjingalwazi waseRashiya, uV. Kovalenkov. Nangona kunjalo, utshintsho lwengcongolo lwalunelungelo elilodwa lomenzi ngo-1936 ngu-WB Ellwood kwi-Bell Telephone Laboratories eMelika. Imveliso yokuqala yemveliso "I-Reed Switches" yafika kwimarike kwi-1940 kwaye ekupheleni kwe-1950, ukudalwa kwee-quasi-electronic exchanges kunye nejelo lokuthetha elisekelwe kwi-teknoloji yokutshintsha kweengcongolo yasungulwa. Ngomnyaka we-1963 iNkampani yeBell yakhupha inguqulelo yayo - uhlobo lwe-ESS-1 olulungiselelwe ukutshintshiselana kwe-intercity. Ngo-1977, malunga ne-1,000 yotshintshiselwano nge-elektroniki yolu hlobo lwalusebenza kulo lonke elase-USA Namhlanje, iteknoloji yokutshintsha ingcongolo isetyenziswa kuyo yonke into ukusuka kwi-aeronautical sensors ukuya kwizibane ezizenzekelayo zekhabhathi.
Ukusuka kulwazi lolawulo lwemizi-mveliso, ukuya kutsho kummelwane uMike efuna nje isibane sokhuseleko ukuba sikhanyise ebusuku ukuze simxelele xa umntu ekufutshane kakhulu nekhaya, zininzi iindlela zokusebenzisa ezi switshi kunye nezinzwa. Ekuphela kwento efunekayo yintlantsi yobukrelekrele bokuqonda ukuba eyona misebenzi ixhaphakileyo yemihla ngemihla inokwenziwa njani ngcono ngokutshintsha okanye isixhobo sokuva.
Iimpawu ezizodwa zokutshintsha kweengcongolo zibenza babe sisisombululo esikhethekileyo kuluhlu lwemingeni. Ngenxa yokuba akukho kunxitywa koomatshini, isantya sokusebenza siphezulu kwaye ukuqina kuyalungiswa. Uvakalelo lwazo olunokubakho luvumela abenzi boluvo bokutshintsha ingcongolo ukuba bafakwe nzulu ngaphakathi kwindibano ngelixa besenziwa ngumazibuthe olumkileyo. Akukho mbane wombane ofunekayo kuba uvulwe ngoomatshini. Ngaphezu koko, iimpawu ezisebenzayo zokutshintsha kweengcongolo zibenza bafaneleke kwi-atmosphere enzima, njengomothuko kunye neendawo zokungcangcazela. Ezi mpawu zibandakanya ukusebenza okungaqhagamshelwanga, abafowunelwa abatywinwe ngokwe-hermetically, ukujikeleza okulula, kunye nokuba i-magnetism esebenzayo ihamba ngqo kwizinto ezingezizo i-ferrous. Ezi zibonelelo zenza utshintsho lwengcongolo lugqibelele kwizicelo ezingcolileyo kunye ezinzima. Oku kubandakanya ukusetyenziswa kwezixhobo zoluvo lwe-aerospace kunye neesensi zonyango ezifuna ubuchwepheshe obunobuthathaka kakhulu.
Ngo-2014, i-HSI Sensing iphuhlise itekhnoloji entsha yokutshintsha ingcongolo kwiminyaka engaphezu kwama-50: iswitshi yokwenyani ye-B. Ayiloswitshi ye-SPST elungisiweyo yefom C, kwaye ayisiyiyo iswitshi enomkhethe ngokwemagnethi ye-SPST. Ngobunjineli bokugqibela ukuya esiphelweni, ineencakuba zengcongolo eziyilwe ngokukodwa eziphuhlisa ngobuqhetseba obufanayo phambi kommandla wemagnethi osetyenziswa ngaphandle. Xa i-magnetic field inamandla aneleyo amandla okugxotha aphuhliswe kwindawo yoqhagamshelwano atyhala amalungu amabini engcongolo kude omnye komnye, ngaloo ndlela aphule uqhagamshelwano. Ngokususwa kwendawo yamagnetic, i-bias yabo yendalo yomatshini ibuyisela uqhagamshelwano oluqhelekileyo oluvaliweyo. Olu luphuhliso lokuqala lokwenene lokutshintsha itekhnoloji yengcongolo kumashumi eminyaka!
Ukuza kuthi ga ngoku, i-HSI Sensing iyaqhubeka ukuba ziingcali zeshishini ekusombululeni iingxaki zabathengi kumngeni kwizicelo zoyilo lokutshintsha kweengcongolo. I-HSI Sensing ikwabonelela ngezisombululo zokwenziwa ezichanekileyo kubathengi abafuna umgangatho ongaguqukiyo, ongalinganiyo.
