      Can anyone tell me how the external switch wiring on a TRS connector ( tip, ring, sleeve) translates to switch number 1,2,and 3 ?

      Thanks in advance

      Tip = 1, Ring = 2, T+R = 3. Sleeve is usually the ground for all three buttons.

      Are there any diodes required?

      Thanks again

      Yes, two 1N4148 that should be wired with the stripes pointing toward the third switch. I’ve attached a schematic.
