Review Limits
Placing a disconnect switch in series with stepper winding leads would not be a good long term idea. It would de-energize the motor, but tinyG would have no idea it was disconnected and would continue to run whatever Gcode job was running at the time.
Installing the limit switches per the Wiki would logically de-energize the motors.
Stopping or pausing a running Gcode job is non trivial and is typically handled by the CAM layer (machine controller) software. Chilipeppr and CNC.js are typical CAM environments for tinyG, but there are others.
