I don't have anything to sketch into a PC handy.
The circuit is easy to describe. You need a NO pushbutton, labled reset. Attach it to power and then to the coil on a double pole relay,labled MCR for master control relay. Now put Estop circuit power to one of the poles on MCR. From the NO side of this pole, wire all your Estop buttons in series and then terminate at the MCR coil.
How it works: push reset button and MCR coil closes. When button is released, the coil is latched in because power is now going through the NO contact and through all the Estop buttons back to the coil. Push an Estop button and the circuit is broken, openning the MCR coil.
Now, take the other pole on MCR and put it in front of any coils or relays you want to break when the Estop is pressed.
