Summary: How do I trigger the flash at the end of an exposure?

I am interested in triggering a flash at the end of a time
exposure.  I will be using a camera with an electronic shutter
(Nikon2020).  I would like to use a switch which will initially
open the shutter when the switch is closed.  When the switch
is opened following the exposure, I would like the shutter
to remain open for a short period of time after this while the flash
is triggered.  The camera shutter would then close.  If
anyone could suggest a simple circuit for doing this I would be
most appreciative.  Thanks.
