• 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
• 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

Could you move the NC pin to the left such that its contact point (the end where a wire can attach) coincides with the symbol outline. (or is within the symbol outline)

@poeschlr Can this be merged, or should the version be reset to 2.3 (see #191) ... the symbols look good (IMHO)
