AC source symbol in TikZ circuits.ee.IEC library

Question

I can draw an AC source manually:

\begin{tikzpicture}
  \draw (0,0) sin (1,1) cos (2,0) sin (3,-1) cos (4,0);
  \draw (2,0) circle (2.5);
\end{tikzpicture}

How do I declare an ACsource symbol so that I can just write the following, or something similar and more correct:

\draw (0,5) to [ACsource={volt=220}] (5,5);

Also, when I am able to declare it as a symbol, will it already behave the same way as the other default symbols in the circuits library? To illustrate, will it behave like this resistor, drawing connector lines and labels in the appropriate places? I also want the ACsource to be the proper size that obeys keys like small circuit symbols, huge circuit symbols, etc.

\draw (0,0) to [resistor={ohm=5}] (5,0);

In response to @morbusg's answer:

I'm using LaTeX. Here's my MWE:

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{circuits.ee.IEC}
\tikzset{circuit declare symbol = ac current source}
\tikzset{%
          ac current source IEC graphic/.style={%
            circuit symbol lines,
            circuit symbol size = width 2 height 2,
            shape = generic circle IEC,
            /pgf/generic circle IEC/before background={%
              \pgfpathmoveto{\pgfpoint{-0.8pt}{0pt}}
              \pgfpathsine{\pgfpoint{0.4pt}{0.4pt}}
              \pgfpathcosine{\pgfpoint{0.4pt}{-0.4pt}}
              \pgfpathsine{\pgfpoint{0.4pt}{-0.4pt}}
              \pgfpathcosine{\pgfpoint{0.4pt}{0.4pt}}
              \pgfusepath{stroke}
            },
            transform shape
          }
}
\tikzset{%
          circuit ee IEC/.append style={%
            {set ac current source graphic = ac current source IEC graphic}
          }
}

\begin{document}
  \begin{tikzpicture}[circuit ee IEC]
    \draw node [ac current source, info=230V] {};
  \end{tikzpicture}
\end{document}

When I try to compile that, I'd get the following error:

Package pgfkeys Error: I do not know the key '/tikz/set ac current source graphic = ac current source IEC graphic' and I am going to ignore it. Perhaps you misspelled it.

@morbusg's solution works perfectly with Plain TeX, but I'm using LaTeX. Perhaps I'm missing something?

Answer 1

I found a solution that perfectly suits my requirements.

\documentclass{minimal}

\usepackage{tikz}
\usetikzlibrary{circuits.ee.IEC}
\tikzset{circuit declare symbol = ac source}
\tikzset{set ac source graphic = ac source IEC graphic}
\tikzset{
         ac source IEC graphic/.style=
          {
           transform shape,
           circuit symbol lines,
           circuit symbol size = width 3 height 3,
           shape=generic circle IEC,
           /pgf/generic circle IEC/before background=
            {
             \pgfpathmoveto{\pgfpoint{-0.8pt}{0pt}}
             \pgfpathsine{\pgfpoint{0.4pt}{0.4pt}}
             \pgfpathcosine{\pgfpoint{0.4pt}{-0.4pt}}
             \pgfpathsine{\pgfpoint{0.4pt}{-0.4pt}}
             \pgfpathcosine{\pgfpoint{0.4pt}{0.4pt}}
             \pgfusepathqstroke
            }
          }
        }

\begin{document}
  \begin{tikzpicture}[circuit ee IEC]
    \draw (0,0)    to [ac source={info={110V 60Hz},near start},resistor={near end}] (3,0);
    \draw (0,-1.5) to [ac source={volt=220,near start}, inductor={near end}]        (3,-1.5);
  \end{tikzpicture}
\end{document}

Answer 2

This first one is a Plain-TeX version which has some extra definitions for "including" the ac source graphic as a toggleable (IEC/US/etc.) shape for circuits.ee. This is not necessary; see further below for a stripped-down LaTeX-version.

\input tikz
\usetikzlibrary{circuits.ee.IEC}
\tikzset{circuit declare symbol = ac current source}
\tikzset{ac current source IEC graphic/.style={
    circuit symbol lines,
    circuit symbol size=width 2 height 2,
    shape=generic circle IEC,
    /pgf/generic circle IEC/before background={
    \pgfpathmoveto{\pgfpoint{-0.8pt}{0pt}} 
    \pgfpathsine{\pgfpoint{0.4pt}{0.4pt}} 
    \pgfpathcosine{\pgfpoint{0.4pt}{-0.4pt}} 
    \pgfpathsine{\pgfpoint{0.4pt}{-0.4pt}} 
    \pgfpathcosine{\pgfpoint{0.4pt}{0.4pt}} 
    \pgfusepath{stroke}
    },
    transform shape
  }
}
\tikzset{circuit ee IEC/.append style=
  {set ac current source graphic = ac current source IEC graphic}
}

\tikzpicture[circuit ee IEC]
  \draw node[ac current source, huge circuit symbols,info=230V] {};
  \draw (1,0) node[ac current source, small circuit symbols,info=230V] {};
\endtikzpicture
\bye

EDIT: LaTeX (without the extra definitions):

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{circuits.ee.IEC}
\tikzset{ac source/.style={
  circuit symbol lines,
  circuit symbol size = width 2 height 2,
  shape = generic circle IEC,
  /pgf/generic circle IEC/before background={
    \pgfpathmoveto{\pgfpoint{-0.8pt}{0pt}}
    \pgfpathsine{\pgfpoint{0.4pt}{0.4pt}}
    \pgfpathcosine{\pgfpoint{0.4pt}{-0.4pt}}
    \pgfpathsine{\pgfpoint{0.4pt}{-0.4pt}}
    \pgfpathcosine{\pgfpoint{0.4pt}{0.4pt}}
    \pgfusepath{stroke}
  },
  transform shape
}}
\begin{document}
  \begin{tikzpicture}[circuit ee IEC,small circuit symbols]
    \node[ac source,volt=230] {};
  \end{tikzpicture}
\end{document}
