Ukuhlolisisa
Isithiyo sokuphepha esihlukanisiweko esinokukhipha i-transistor yokungena kweswitshi, oku ihlukanisa begodu idlulisele amatshwayo wokufaka avela ebantwini abatjhugululako nofana eduze amatjhuguluko eendaweni eziyingozi ukuya endaweni ephephileko nge-transistor yokukhipha ngokusebenzisa isithiyo sokuphepha. Ukutholwa kwephutha lelayini kufezwa ngokusebenzisa I-LED phezulu kwemojuli. Iswitjhi yokudayela yemodyuli iyasetjenziswa ukusetha ukufaka nokukhipha ngaphakathi kwesigaba nofana ukulawula okubuyela emuva, kanye nokuvumela nofana ukhubaze umsebenzi wokutjengisa i-alamu yokuthola amaphutha welayini.
Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, ngamandla ahlukanisiweko ukuphakela, ukufaka, nokukhipha amatheminali.

Ukutholwa kwephutha lelayini(LFD)
Abasebenzisi bangakhetha ihlangothi elithi "VULA" leswitshi phezulu kwemodyuli ukuvumela umsebenzi wokuthola amaphutha begodu utjengise i-alamu nge- isibani esibomvu se-LED. Umtjhini wokufakwa endaweni>7mA, i-alamu yesekhethi emfitjhani (SC); Umtjhini wokufaka wendawo
ukufaka kokuthintana kutlhoga umsebenzi wokuthola amaphutha (ukuphuka kwentambo, okufitjhani isekhethi), i-resistor ye-22k Ω kufanele ixhunywe ngokufana emaphethelweni womabili ye-switch, begodu i-resistor engu-680 Ω kufanele ixhunywe ngokulandelana (njengombana kutjengiswa emfanekisweni wokufaka iintambo wokuthintana kweswitjhi II).
