Ukuhlolisisa
Isithiyo sokuphepha esihlukanisiweko esine-transput yokufaka ye-switch, esihlukanisa begodu sidlulisele amatshwayo wokufaka avela ebantwini be-switch nofana ama-switch aseduze eendaweni eziyingozi ukuya endaweni yokuphepha ene-transput yokukhipha ngokusebenzisa isithiyo sokuphepha. Ukutholwa kwephutha lelayini kwenziwa nge-LED phezulu kwemojuli. Iswitjhi yokudayela yemodyuli isetjenziselwa ukusetha ukufaka nokukhipha ngaphakathi kwesigaba nofana ukulawula okubuyela emuva, kanye nokuvumela nofana ukuvala umsebenzi wokutjengisa i-alamu yokuthola amaphutha welayini.
* ukuphakelwa kwamandla wetheminali yebhasi, sibawa uqale isithasiselo ukuthola imininingwana.

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 yeswitjhi, begodu 680 Ω resistor kufanele ixhunywe ngochungechunge (njengoba kutjengiswa emfanekisweni wokufaka iintambo wokuthintana kweswitjhi II).
