I have an AC wall socket, currently controlled by a wall switch. I

socket. Alas I never looked to see how that "split" outlet
configuration was implemented.
Can one inform me, how to make this change? Thanks
What century are you living in? All my sockets have switches on them.

You do know that North American wiring standards, voltages and frequency of
normal AC power for homes. business and industry are quite different from
those of Europe? Your inductive hum is lower and more masculine. I suppose
that's a point of pride for you. ?(?)?

****Simple answers ****
Can I change duplex outlet that one half works of the switch and other being
directly on the line:: “NO” unless you can run additional line, you need
four wires 2 Hot one Neutral and one for Ground, Only then you can split
the duplex, one output hook to hot line and one hook on the line coming from
the switch. This is for 120 Voltage source USA standard Receptacle.
All of the switched outlets I ever wired had the feed at the outlet not the switch. The power to the outlet was daisy chained to the other outlets in the room and a piece of Romex was run to the switch to control the power to one or both sides of the duplex receptacle. Having the feed at the receptacle means you only have to break the hot tab to separate the sides and switch one of them. ?(?)?
Yes, "drop switch" wiring used to be the most common way of switching
outlets, and even cieling lights, but with the code change requiring
the use of 3 wire cable (neutral required in all boxes) it no longer
really makes sense.
Yes Europe power is 50 cycle (Hrz), While USA is 60 cycle (Hrz) . Please
Note; resistive loads can run very efficiently on both powers. For inductive
loads “It will not” Voltage must be reduce apx. 10 to 15%. for American made
motors to run on 50 Hrz. At 50 Hrz motors will draw more current that will
cause overheat and shout down or will burn up..
As for leakage I do not believe that makes any difference with 50 or 60
Herz. However Voltage does make differences, and when it is said leakage
into what across what ???
Remember working with USA 120 Standard and working with 1000 volt (Example)
is big difference.
The 50hz transformers are larger than 60hz transformers. Aircraft power systems often run on 400hz AC power and the transformers in the avionics are much smaller and lighter than the terrestrial 50 and 60 Hertz transformers. ?(?)?
Correct. Also the reason a 10 amp switch mode power supply is less
than half the size and weight of a 2 amp linear. The inductance of a
coil is a lot higher at gigh frequencies than at low - so the
"effective resistance" of say a 10 turn primary of #18 wire is a lot
lower at 2.5khz than a 2000 turn primary of #22 wire at 60 hz.
