CircuitikZ – How to Draw a Special Element in CircuitikZ

circuitikzpgfplots

I need to draw a wire that looks like

That is the symbol my lecturer uses for the Josephson junction. I googled a bit and it seems to be the commonly used symbol for such an element, so it would be useful to have a way to implement it in circuitikz.

I use pgfplots as well as tikzexternalize, which forces me to start the circuitikz environments with \begin{tikzpicture}, if that makes any difference.

EDIT (as requested in comment): I would like to use the element between a and d in the following circuit:

\begin{figure}[ht]
  \centering
\begin{tikzpicture}
      \draw (0,0)
        node[label={[font=\footnotesize]above:a}] {}
      to[short,*-*] (1.732,1)
        node[label={[font=\footnotesize]above:d}] {};
      \draw (0,0)
      to[C=$C$,*-*] (-1.732,1)
        node[label={[font=\footnotesize]above:b}] {};
      \draw (0,0)
      to[L=$L$,*-*] (0,-2)
        node[label={[font=\footnotesize]east:c}] {};
\end{tikzpicture}
    \caption{Explaining conventions}
\end{figure}

The code produces the following in my document:

Using a native circuitikz symbol known as barrier:

\documentclass{article}
\usepackage{circuitikz}
\begin{document}

\begin{figure}[ht]
  \centering
\begin{tikzpicture}
      \draw (0,0)
        node[label={[font=\footnotesize]above:a}] {}
      to[barrier,*-*] (1.732,1)
        node[label={[font=\footnotesize]above:d}] {};
      \draw (0,0)
      to[C=$C$,*-*] (-1.732,1)
        node[label={[font=\footnotesize]above:b}] {};
      \draw (0,0)
      to[L=$L$,*-*] (0,-2)
        node[label={[font=\footnotesize]east:c}] {};
\end{tikzpicture}
    \caption{Explaining conventions}
\end{figure}

\end{document}

MWE:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows, circuits.ee.IEC, positioning}
\usepackage[american voltages, american currents,siunitx]{circuitikz}

\begin{document}
\begin{tikzpicture}[circuit ee IEC,american,x=2cm,y=2cm, semithick, every info/.style={font=\footnotesize}, small circuit symbols, set resistor graphic=var resistor IEC graphic]
        \draw (0,0) node[shape=ground]{}
    to [V, invert, l=\mbox{$V_S$}, a={\SI{5}{\volt}}] (0,1)
    to [cspst , l =$t_0$] (1,1)
    to [L, l=\mbox{$L$}, a=\SI{1}{\henry}] (2,1)
    to [R, l=\mbox{$R$}, a=\SI{47}{\ohm}] (3,1)
    to [C, l_=\mbox{$C$}, a^=\SI{247}{\pico\farad}] (3,0)
    to (3,0) node[shape=ground]{};
\end{tikzpicture}
\end{document}

[Tex/LaTex] use circuitikz picture inside tikzpicture

You are using circuitikz inside a node. The circuitikz environment is nothing but a tikzpicture environment in disguise. Using tikzpicture inside a node is not a good idea and it will cause odd things. You can use a box instead. I have created \mycircuita and \mycircuitb boxes (with 0 and 20V) and used them inside the callout node.

As an alternative, you could also use pic facility of tikz but using a box is simpler in this case.
