Free AutoCAD telephone, selector and sound symbols (DWG), IEC 60617-9 style

About IEC 60617-9

IEC 60617 is the international standard for graphical symbols for diagrams. Part 9 covers telecommunications: switching and peripheral equipment, the symbols for exchanges, telephone sets, telegraph apparatus, sound and recording equipment. This library follows the figures of that part.

These symbols are our own drawings after the figures of the standard. They are not copied from it, and the library is not certified against it. Check them against the standard, your company standard or your customer’s legend before you decide to use a symbol.

Frequently asked questions

How do I draw a selector?

Use the block of the type you need, for example “Single-motion, homing” or “Two-motion selector, homing”. The wiper, the arc and the outlet are already drawn. The individual parts (wiper, arc, bank, level) are also separate blocks, so you can build a type that is not here.

Where are antennas, waveguides and modulators?

They belong to telecommunications transmission, part 10 of the standard, and are not in this library. This one holds the switching, telephone and sound symbols.

Can I use the symbols in commercial projects?

Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty.

Why do the indication symbols have no reference?

Recording, erasing, tape, drum and similar indications are not devices; they are marks that go inside the symbol of a recorder, a head or a stage. They only have a remarks field, so you can combine them without extra attributes in the drawing.

Can I change a symbol or add attributes?

Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.

Where do I find a ready-made set of these symbols for AutoCAD?

AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.
