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.

15 mA for the MOC3041. The 39 ohm resistor and 0.01 F
capacitor are for snubbing of the triac and may or may not
be necessary depending upon the particular triac and load
used.

tors, R1 and R2, are optional 330 ohms.
NOTE: This optoisolator should not be used to drive a load directly.
Typical circuit for use when hot line switching is required.
