looking for the 2d electrical symbols lib
Electrical symbols (1.1 MB - 72 models
(created by Dorin)

looked here (ticket #325 and 3D Models)
'These libraries (and other ones) are available as SH3F files that you can download in the ticket #325 of the 3D Models Contributions Tracking System at SourceForge.net.'

but it doesn't seem to be there, at least by the name
'electrical symbols'
