Typical circuit for use when hot line switching is required.
In this circuit the “hot” side of the line is switched and the
load connected to the cold or neutral side. The load may be
connected to either the neutral or hot line.

part, 15 mA for the MOC3061, 10 mA for the MOC3062,
and 5 mA for the MOC3063. The 39 ohm resistor and 0.01
µF capacitor are for snubbing of the triac and may or may
not be necessary depending upon the particular triac and
load used.
