I thought I would add a little more food for thought. Attached is the schematic and what I think is the mute switch is item 86, from the CT of the volume control to ground. I could be wrong and often are. If it is true I don't see how the that springy thing is going to do it without some wire going to it attached to the CT of the volume control.
