Iswitshi yokuguqula yinto eqhelekileyo yolawulo kwindawo yombane, esetyenziselwa ukufumanisa ukuhamba kwamanzi okanye izinto eziqinileyo kwimibhobho kunye nokulawula ukuqala kunye nokumiswa kwesixhobo ngokusekelwe ekuguquguqukeni kwamanzi okanye ukuhamba kwezinto. Ukutshintsha kokutshintsha kusetyenziswa ngokubanzi kwimizi-mveliso ezenzekelayo, unyango lwamanzi, ukulungiswa kokutya, kunye nezinye iindawo, kunye nemisebenzi yabo yokulawula esebenzayo kunye nezinzileyo inika inkxaso ebalulekileyo kwimveliso kunye neenkqubo. Eli nqaku liza kuxubusha inkcazo, umgaqo, indlela yokusebenza, indawo yesicelo, iimpawu, kunye nesikhokelo sokhetho lokuguqula utshintsho.
Ukutshintsha kokutshintsha licandelo lombane elisebenzisa ukuguquguquka kulwelo okanye ukuhamba kwezinto eziqinileyo ukufikelela kulawulo. Ngokufumanisa ukuguquguquka kulwelo okanye ukuhamba kwezinto kumbhobho, iswitshi yoguqulo inokuqinisekisa ngokuchanekileyo ubukho okanye ukungabikho kwemathiriyeli, imeko yokuhamba kwayo, kunye nolunye ulwazi, kwaye ilawule ukusebenza kwezixhobo ezinxulumeneyo ngokufanelekileyo. Ukutshintsha kokutshintsha ngokuqhelekileyo kubandakanya inzwa, isiphaluka solawulo, kunye ne-actuator, kwaye ibonakaliswe ngovakalelo oluphezulu kunye nokuphendula ngokukhawuleza.
Umgaqo osebenzayo wokutshintsha uguqulelo lusekwe ikakhulu kwimpembelelo yokuguquguquka kwezinto kwi-detector. Xa uguquguquko kulwelo okanye ukuhamba kwezinto kumbhobho kufikelela kwinqanaba elithile, iswitshi yokuguqula ibona umqondiso wokuguquguquka ngesixhobo soluvo kwaye yenza isigwebo esisekwe kumda osetwe kwangaphambili. Ngokubanzi, iswitshi yokuguqula iqhuba i-actuator ehambelanayo ngomqondiso wokuphuma ukufezekisa ukuqalisa kunye nokumisa ulawulo lwesixhobo.
