Typical circuit (Fig 12, 13) 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.

capacitor are for snubbing of the triac and may or may not be necessary depending upon the particular triac and
load used.
