There are time delay relays (time delay on dropout ) that will do this or
you could use a solid state relay with the control of the relay from the
fast dropout circult but with an electronic time delay before the loss of
input turns off the relay.

I have a switch that cuts the power to 2 different AC circuits. I need
one of those two to stay on for a few seconds after the other is off.
Is there some easy circuit to do this. The current requirements are
about 15A at 110V
