I have copied an example from the tikz manual, but it fails to compile





                circuit ee IEC,
                every info/.style={font=\footnotesize},
                small circuit symbols,
                set resistor graphic=var resistor IEC graphic,
                set diode graphic=var diode IEC graphic,
                set make contact graphic= var make contact IEC graphic]
% Let us start with some contacts:
\foreach \contact/\y in {1/1,2/2,3/3.5,4/4.5,5/5.5}
  \node [contact] (left contact \contact) at (0,\y) {};
  \node [contact] (right contact \contact) at (1,\y) {};

Some samples of the errors messages:

Package pgfkeys Error: I do not know the key '/tikz/circuit ee IEC'

Package pgfkeys Error: I do not know the key '/tikz/set resistor graphic'

Try adding the circuits.ee.IEC library (hope I remember correctly I don't have the manual right now). – cjorssen Mar 18 '12 at 9:21

It's a small error in the documentation. The documentation says


but you need


(missing s)

Than the example works
