You need a stereo jack that also switches a circuit — mute the amp when the cable's out, cut the signal when the plug's in. This Jaycar 3.5mm stereo switched PCB socket does both in one footprint. Solder it to your board, wire the switching contacts, and you've got clean on/off control without hunting for a separate momentary switch. One part, two jobs, done
