I think (note the weasel word 
) this will do what you want. It is basically the alps encoder from core with the switch added (and a variety of other things such as rescaling, breadboard, schematic and pcb modified to add the switch). I assumed the original pads were the correct size for the alps parts because the layout was similar (if missing the switch terminals). Before ordering boards with this pcb footprint, print out a copy and check alignment and hole size against the real part (I don’t have one to do that with). Note the called for square holes for the mounting pins are round holes in this case as Fritzing (AFAIK) doesn’t do square holes.
