Where can I find on/off symbol?

Question

Where do I find the on/off symbol of electronics? enter image description here

Check here http://www.ctan.org/tex-archive/info/symbols/comprehensive/ — Sigur, Feb 02 '14 at 18:21
Also see How to typeset special Apple Mac keyboard symbols?; applekeys provides \power which is similar. — Werner, Feb 02 '14 at 18:35
Is it really still appropriate to always link to http://www.ctan.org/tex-archive/info/symbols/comprehensive/ ? The document is outdated by five years. Nowadays, with unicode, fontspec, and also TikZ we have more options than looking it up there and loading packages. — Ingo, Feb 03 '14 at 07:59

The package fontawesome provides a lot of useful symbols:

% arara: lualatex
\documentclass{article}
\usepackage{fontawesome}
\begin{document}
\faOff
\end{document}

The fontawesome package contains a \faoff or \faicon{off} command for this. It is an OpenType font, so that you need fontspec and xelatex or lualatex to use it. Maybe otftotfm and cfftot1, from the LCDF type tools, might allow to obtain a type 1 version usable with (pdf)latex. – Bernard Feb 02 '14 at 18:50

\documentclass[pstricks,border=12pt]{standalone}

\begin{document}
\begin{pspicture}[linewidth=1,linecap=1](6,6)
    \psarc(3,3){2.5}{125}{55}
    \psline(3,3)(3,5.5)
\end{pspicture}

Nice and short! – Svend Tveskæg Feb 02 '14 at 18:55
line cap of the arc must be round too. ;) – percusse Feb 02 '14 at 20:03

@percusse: It is not sharp anymore and becomes safe for children. – kiss my armpit Feb 05 '14 at 07:19

And a tikz solution that can also be used as standalone symbol graphics:

\documentclass{standalone}
\usepackage{tikz}

\newlength\unit
\setlength{\unit}{20pt}

\begin{document}
\begin{tikzpicture}[
  x=\unit,
  y=\unit,
  radius=\unit,
  line width=.4\unit,
  line cap=round,
]
  \draw[overlay]
    (0,1.2) -- (0,0)
    (130:1) [overlay] arc[start angle=130, delta angle=280]
  ;
  \path[use as bounding box] (-1.2,-1.2) (1.2,1.4);
  % arc is is taking the points of the internally used Bézier
  % curves into account for the bounding box
\end{tikzpicture}
\end{document}

Remarks:

The bounding box is specified separately, because arc uses the points of the internally used Bézier curve for the bounding box.
I have used rounded line caps, they look better for my taste.

You can drawing it yourself using PSTricks.

With 'sharp' corners:

\documentclass{article}

\usepackage{pstricks-add}

\newcommand*\OnOff[1]{%
\begin{pspicture}(6,6.5)
 \psset{
   dimen = middel,
   linecolor = #1,
   fillstyle = solid,
   fillcolor = #1
 }
  \psRing(3,3)[125,55]{2}{3}
  \psarc(3,3){0.5}{180}{360}
  \psframe(2.5,3)(3.5,6)
  \psarcn(3,6){0.5}{180}{0}
\end{pspicture}}

\begin{document}

\begin{center}
  \OnOff{black}
  \OnOff{blue}
  \OnOff{red}
  \OnOff{yellow}
\end{center}

\end{document}

With 'round' corners:

\documentclass{article}

\usepackage{pstricks-add}

\newcommand*\OnOff[1]{%
\begin{pspicture}(6,6.5)
 \psset{
   dimen = middel,
   linecolor = #1,
   fillstyle = solid,
   fillcolor = #1
 }
  \psarc(!3 2.5 130 cos mul add 3 2.5 130 sin mul add){0.5}{310}{130}
  \psRing(3,3)[130,50]{2}{3}
  \psarc(!3 2.5  50 cos mul add 3 2.5  50 sin mul add){0.5}{50}{230}
  \psarc(3,3){0.5}{180}{360}
  \psframe(2.5,3)(3.5,6)
  \psarcn(3,6){0.5}{180}{0}
\end{pspicture}}

\begin{document}

\begin{center}
  \OnOff{black}
  \OnOff{blue}
  \OnOff{red}
  \OnOff{yellow}
\end{center}

\end{document}
