Zingaki izimpawu zokujika eziyimizuzwana emithathu?
Isignali yokujika ikhala izikhathi ezi-3, okuyimizuzwana emi-3 ngesikhathi, ngoba imvamisa evamile ye-flash ye-relay yesignali yokujika icishe ibe yi-1 Hertz, okungukuthi, izikhathi ezingama-60 ngomzuzu, kanti isignali yokujika ikhanya cishe isikhathi esi-1 ngomzuzwana. Uma kukhona ukwanda okungazelelwe kwemvamisa, kungenzeka ukuthi isignali yokujika eseceleni noma isekethe yayo inephutha. Iswishi yesignali yokujika yemoto evamile ivame ukufakwa ohlangothini lwesobunxele lwesiteringi, indlela yayo yokusebenza ingafingqwa ngokuthi "kwesokudla" ngaphansi kwamagama amane "kwesobunxele", lapho isignali yokujika ijika (ngokwewashi) iye kwesokudla, idlale phansi (ngokuphambene newashi) ukuze ijike kwesobunxele. Kodwa ngokuthuthuka kwemoto, manje izimoto eziningi sezikhulise iswishi ye-flash ephindwe kabili emsebenzini wokudayela okusheshayo we-"once touch three flash". Umshayeli umane "uthinte" i-lever, bese isibani sokujika sikhanya kathathu bese sicima. Ngale ndlela, umnikazi angagwema inkinga yokuvala isignali yokujika lapho edlula.
