Hi Max:

In industrial equipment an Emergency Stop Button controls a relay that has the capacity to interrupt the current. Usually it is wired to "fail to OFF". This would mean current would flow through the Stop Button to hold the relay "ON". Thus if the wire to the Stop Button broke, the machine would forced to stop.
