The switching input transistor output signal isolator e fetola lets'oao la ho kenya ho tsoa ho sehokelo sa switch kapa switjha e haufi hore e be sehlahisoa sa transistor ka ho itšehla thajana. Mosebetsi oa ho lemoha phoso ea mohala o bontšoa ke lebone la LED ka holim'a module. Phetoho ea module e sebelisetsoa ho khetha mohato oa mocha le hore na mosebetsi oa ho lemoha phoso oa mohala oa hlokahala.
Sehlahisoa sena se hloka ho tsamaisoa ka boikemelo, 'me li-terminals tsa phepelo ea motlakase, ho kenya le ho tsoa li arotsoe.
