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