Folks,
I recently replaced the shaver socket in the bathroom, and boy ... do I feel cheated. The old unit had two outputs one labeled 110v the other
220v with an external switch to select one or the other. I have both an electric toothbrush and an electric shaver and I was fed up having to keep track of which was being charged and for how long. So I replaced it with a 2 gang MK shaver socket from B&Q which had two outputs and no switch, one marked 110 and 220. Since both my devices will run on either 110 or 220 I intended to plug in both simultaneously and it would not matter about the different supply levels.However it turns out the MK unit was switched, it had an hidden internal mechanism operated by insetting a plug. Only one of the sockets can be used at a time. A real pain. This was not marked on the packaging anywhere. I phoned MK and they gave all kinds of guff as to why things were the way they were. Interestingly the support guy did admit that these devices were designed decades ago and were not intended for continuous use, even if this continuous use only involved having to support trickle chargers. Some shaver sockets tended to overheat and would cut out, if say a shaver was left continuously plugged in! This has apparently been fixed.
However my question is has anybody hacked these units to allow both sockets to be used simultaneously? I am interested in any thoughts as to wiring the transformer's output to both sockets, and bypassing or disabling the switch. Assuming the transformer only has one secondary winding which is tapped to provide the 110v output. Should I use the 110 or 240 winding?
Thoughts?
