This package contains a collection of symbols for typesetting electrical wiring diagrams for relay control systems. The symbols are meant to be in agreement with the international standard IEC-60617 which has been adopted worldwide, with perhaps the exception of the USA. It extends and modifies, when needed, the TikZ-libray circuits.ee.IEC. A few non-standard symbols are also included mainly to be used in presentations, particularly with the beamer package.
