Working Principle
The 3.5mm female stereo jack provides an electrical interface between a stereo audio plug and the PCB. When a compatible 3.5mm TRS plug is inserted:
- The Tip contact carries the left audio signal.
- The Ring contact carries the right audio signal.
- The Sleeve contact provides the common ground connection.
The internal spring contacts ensure a firm connection, enabling stable and low-noise audio transmission.
