Fair enough - words are not exactly the best way to transmit this type of information. It's amazing we get as much across on this forum as we do manage.

FWIW, I disagree with Don and Harry. Whilst it might send the power through lots of connections and so forth, it's a simple method, is cheap to do (and cheap to repair), and uses the most basic, easily available parts. That makes it a good fit for a box that spends its life getting stamped on on that beer-soaked floor Harry mentioned.
