Electricity does take the path of least resistance, this is a known fact. In your example the 0.5 ohm coil would get the hot, the other would not. A negligible amount would flow through the other coil proportional to their difference in resistance. If we can't agree on this basic point then further explanation of what I'm postulating is difficult.
The outer case of the your mech mod is the negative path of the circuit. When you fire it you don't get a shock, because your hand offers vastly more resistance than the metal of the tube. There may be miliamps going through your hand, but there may be 15-20 amps running through the tube body.
The gray is the button body, the green is the button, the blue is the spring. The red indicates the difference in contact area and therefore the 'easiest' path for the electricity to flow. Now imagine removing the springs and replacing them with a magnetic field. The switch still works exactly the same. As I said before the job of the spring/magnet is to return the button to it's original position, not to carry the electricity.
