In this circuit the “hot” side of the line is switched and the load connected to the cold or ground side.
The 39 Ω resistor and 0.01 μF capacitor are for snubbing of the triac, and the 470 Ω 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.
