The answer is you do not need to unplug the switch or I can think of no reason to unplug it to do fuel pump and no if the switch trips or comes unplugged then the car would shut off at that time you would not be able to drive it. One of the wires is power from the fuse the other is power to the pump so if one is out the car will not run.
