We are using this audio jack in our design. I am having trouble understand the schematic of this audio jack. My understanding is that
- Pin 5 and Pin 4 : Audio left and right
- Pin 2 or Pin 3 : Ground or Mic
- Pin 1: detect
Can anyone confirm my understanding? I think that the switch is normally open and pin 3 will short with pin 1 when the jack is inserted.
