Default Schematic symbols - where to find

I'm searching for schematic symbols for electrical schematic drawings, can't find any good collections. I'm going to draw some electrical drawings with motors, sensors, switches etc but I'm not sure how the symbols look like. I'm only interested in ISO (European) symbols. Anyone who have a clue?

They would have to fit into whatever drawing program you are / will be using.

Once again, Google is your friend!

Here is an example:

I know that there exist AutoCad compatible librarys of the NEN5152 (more than 1500 elektrotechnical symbols).

Use Google, and type "NEN5152", or type "electrical ISO symbols".

Sevaral sellers has demo's.

I hope this information is relevant for you.

New IPC standard regarding schematic symbols IPC-2612-1 is around, I do belive it can be downloaded for evaluation if you look aroun. If not PM me and I'll zip you a copy. It covers most symbols and may finaly start harmonising symbols used. We are adopting it along with IPC-7351 footprint libraries (our friends at PCB matrix) as we have customers all over, each with thier own views on how a resistor should be drawn, so where possible now I'll stick to an IPC standard, it avoids a lot of problems.
Out of curiosity what system will they be used on.

what are you using for software? LTSpice is good for windows OR linux (running under wine). i also use gEDA in linux which has a huge symbol library, and huge libraries of other symbols available on the web. if you're a windows user, i think there might be a windows port of gEDA. gEDA also comes with a PC board layout program.

I use mainly Cadstar, and have numerous schematic symbols + Almost complete IPC-7351 footrprints. Orcad and Allegro used less frequently these days.
