ngs on startup and run.....with this info

snip

Thanks for the replies. Ours is a two wire pump, so no controller. Before I
posted here yesterday, I added a magnetic contactor to handle the pump load as
you mention with the pressure switch only handling the load of the magnetic
coil. I am thinking this will solve my immediate problem, but was still
looking for ideas as to why I am having the problem.

thanks everyone,
Bobby

Newer motors, particularly, high efficiency ones, have a larger
inrush current. Possibly they also have a larger "kick" when the
starter (your pressure switch) drops out.

The contactor was a good idea. You may want to consider adding a
suppressor to your contactor coil to protect the contacts of the
pressure switch. See for examples:
