There is a data sheet for all 1/4 3.5mm mono jacks here. I ordered mine from aliexpress so they didn’t come with a data sheet but found something similar https://www.mouser.com/ds/2/18/amphenol_phone_plugs_jacks-1157261.pdf
I have uploaded a picture of the jacks I am currently using.
I have updated my circuit too, need to add the jacks now Chewie circuit.fzz (81.6 KB)
