I'm attempting a little project where I can have three 3.5mm jack inputs, then a switch to direct to a single 3.5mm headphone output.
Based on a simmilar Instructables page but attempting to adapt it for three inputs rather than two.
Here's the highly detailed diagram from that page:
Coming across this diagram for a three position switch, I thought I had a plan:
So I've attached all the components and given it a test
But it has become apparent that it works a little more like this:
I'm now coming across diagrams like this one in the bottom right, talking about external jumpers between the pins?
Am I just using the wrong kind of switch, or do I need to re-jig my wiring and add some jumpers in?
Any guidance would be most appreciated.
Thanks.

You have got the right switch terminal diagram but the wrong switch!
Here's a photograph of the correct switch. Note the pin spacing.
You would need to wire the L & R terminals of the output socket to A0 & B0 terminals of the switch.
Like wise with the L & R terminals of the input sockets to A1 & B1, A2 & B2 and A3 & B3 terminals of the switch.
The common terminals of the four sockets are to be interconnected.
