In this circuit the “hot” side of the line is switched and the load connected to the cold or ground side.
The 39 ohm resistor and 0.01µF capacitor are for snubbing of the triac, and the 470 ohm resistor and
0.05 µF capacitor are for snubbing the coupler. These components may or may not be necessary
depending upon the particular and load used.
