I like it a little better when the set of E-Stop switches are the latch.
Use them normally closed and when a wire comes loose the system goes down
rather than leaving you there mashing on that big red button wondering
why it doesn't work. You might not believe it but the whole schematic goes
through your head in less time than it takes the axis to crash.
