3.5 mm mini jack

FiiO M11S Portable Music Player Headphone Jack's Product Operating Principle

1. When a 3.5mm plug is inserted, internal spring contacts are displaced, establishing a secure electrical connection with the plug's terminals.

2. The contacts route audio signals (left, right, and ground) from the printed circuit board (PCB) to the connected headphones or speakers.

3. Engineered with a 3-30N operating force, it provides a firm yet smooth feel, contributing to its long-term durability over thousands of cycles.
