Footprint: KiCad/kicad-footprints#1773

---

All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

• Provide a URL to a datasheet for the symbol(s) you are contributing
• An example screenshot image is very helpful
• Ensure that the associated footprints match the official footprint library
  • A new fitting footprint must be submitted if the library does not yet contain one.
• If there are matching footprint PRs, provide link(s) as appropriate
• Check the output of the Travis automated check scripts - fix any errors as required
• Give a reason behind any intentional library convention rule violation.

The connector lib is for generic symbols of different connector types. I suspect that there will be similar parts out there so my suggestion would be to remove the datasheet and footprint assignment. Set the footprint filter to fit the prefix of the footprint and rename the symbol to CoaxialSwitch_Testpoint (or similar)

Alternative we make a specialized lib for things like that and have fully specified symbols. I am however not convinced that this would be the right move at this point in KiCads development.

The footprint filter should be generic as well

I think you misunderstood what i meant with "generic footprint filter". I would suggest to use the filter CoaxialSwitch*
