Does this unit have an internal switch so that the transformer is not energised unless something is plugged into the faceplate?
Yes it has an internal switch that activates when a plug is put in. Hence, no power used when unplugged. I have 1 for the last 5 years and I'm just about to buy 2 more.
They do 'hum' a bit, but I leave them un-plugged over-night to solve that problem, however, not so bad that I won't buy them.
