Smooth potentiometer - does not isolate grounds between sources.

Works well as either a switch for 2 different sources for a single amp/headphones or for a single source feeding 2 different output devices. Mute switch has NO "bounce" and is quiet.The A/B switch does not isolate grounds between the inputs nor does it have a switch to lift the ground. This is fine for battery powered devices, but can be an issue with 2 sources using switching power supplies or one with a linear supply and the other a switcher. I added a transformer isolation on one input to break ground

Pros
