Re: Emergency stop button -- IMHO

Consider this switch on the wall plug side of the layout. Note that the hot and neutral wires are both connected to the switch itself.
How it works: The "ON" button is a momentary contact, normally open switch which activates a built in solid state relay when pressed. That relay connects the wall plug to your layout. To shut everything down, press "STOP" which disconnects a momentary contact normally closed switch to deactivate the built in relay.
These switches are sold primarily into the power tool market - table saws etc.
