The unloaded portion of the pressure switch was leaking
After replacing the switch it shuts off at 125 then bleeds down to 80psi
I was mistakenly assuming the problem was with my switch, once I changed focus to the check valve I now understand that the check valve is leaking allowing the pressure switch to bleed off pressure out of the tank instead of just relieving pressure in the pump.
A new check valve is on order
