I needed a simple PCB for 3.5mm jacks, I like switchcraft's 35RAP series connectors for audio projects; good value and quality. This PCB incorporates 4 of them with 600 mil spacing.

Each pin goes to a wirepad and there are a few wirepads for ground.

You can see the board used in a project here: https://audiodiwhy.blogspot.com/2024/12/efmkorg770-vcf-build-yes-sound-no.html

The board is designed for Switchcraft 35RAPC2AV mono jacks but could be easily modified to accommodate other PCB mounted single switch jacks or stereo 3.5" jacks.

The footprint was a bit tricky to design in Kicad; I had to experiment with different pad and drill shapes to get the part to fit into the board correctly. I include the custom Kicad footprint below. For the Kicad symbol please use the 3 conductor connector with switch symbol--pin 2 is "hot". Kicad 8 calls the symbol "DC barrel jack with internal switch".
