Touch Switch By IC 4001 & 4020

Circuit Touch Switch By IC CD4001, CD4020
This be touch switch be simple again the circuit. It use integrated digital circuit is important equipment, and use volt power supply low just 9V. By use single metal, it works in the character turn ON and turn OFF. By when touch for the first time turn ON , but enough for the second time turn OFF. The circuit composes IC CD4001 take electric signal from a finger become the digital signal for change. The IC CD4020 be the counts two circuit or the divides circuit by two. Subsequently submit give the transistor drive Load next.
