Fade fades the lighting circuit switch shown in Figure 1-12. The figure for the light switch S, H is accused of lighting. Transistor VT1, VT2 and RC components fade dimming con
trol circuit. Since transistor VTl, V12 must work in DC like state, the circuit and the other with four diodes VDl ~ VD4 bridge rectifier circuit composed of the full-wave DC 220V AC into pulsating voltage supply road work use.
