Electronic touch incandescent lamp dimming system
Source: InternetPublisher:石榴姐 Updated: 2016/07/22
The circuit is mainly made of a special chip SM7232, which controls the switching and dimming of incandescent lamps by touching the M-point touch chip with the human body, with a maximum load power of 500W.
The LED is best installed near the touch chip to play an indicating role in the dark.
R6 and R7 intentionally use two resistors from the perspective of human body safety.
