There are many examples out there for stop/start PB control where the contactor or E-stop relay is enabled by a N.C. E-stop or stop button and reset by a N.O. P.B. that has a retaining contact in parallel with it across the N.O. button.
e.g. Motor Starter Control Circuits
You can use the main contacts for a either motor control or to switch off any necessary E-stop power, most contactors have at least the N.O. auxiliary contact and most will allow additional Aux contacts to be added or clipped on as needed.
