3.5mm Stereo Audio Jack | PCB Mount Headphone Socket丨PJ-3550B

MOTU M2 Audio Interface Headphone Jack's Product Operating Principle

1. When a 3.5mm plug is inserted, internal spring contacts make a secure electrical connection with the plug's tip, ring, and sleeve (TRS) sections.

2. An integrated switch mechanism changes its state upon plug insertion, allowing for functions like speaker muting or signal source detection.

3. The 5-pin configuration routes stereo audio signals (left/right) and ground through the PCB, ensuring stable and clear audio transmission.
