The referenced part was part of the google code base. That repository (and this part) appear to have been corrupted. There was a request a few months ago for anyone that had a non corrupted copy but I’m not aware of any answer. That said, this isn’t like any of the parts we currently have (but is a relatively minor change from one of the stereo jacks) so try this:
3.5mm switching Jack.fzpz (7.5 KB)
Note as always you need to print out the pcb footprint and check it against a real part before ordering boards. The holes are all 1.5mm (they actually want a slot, but I don’t know how to do it in Frtizing and many board houses don’t support it anyway).
