Chotchinga chakutali chokhala ndi switch input transistor, chomwe chimapatula ndikutumiza ma siginecha olowera kuchokera pakusinthana kapena ma switch oyandikira m'malo owopsa kupita kumalo otetezedwa okhala ndi transistor yotulutsa kudzera pachitetezo chachitetezo. Kuzindikira zolakwika za mzere kumatheka kudzera pa LED pamwamba pa module. Kusintha kwa dial kwa module kumagwiritsidwa ntchito kuyika zolowera ndi zotuluka mu-gawo kapena kuwongolera kumbuyo, komanso kuthandizira kapena kuletsa ntchito yozindikiritsa vuto la mzere.
Izi zimafuna magetsi odziyimira pawokha, okhala ndi magetsi akutali, zolowetsa, ndi zotulutsa.
