The Jack Connector

The jack connector (also known as a jack plug or simply "jack") is an electrical connector commonly used to transmit very low-voltage signals, primarily analog audio signals. It was invented in the 19th century for use in telephone switchboards and is one of the oldest electrical connector standards still in use today.

TS Jack: 2 contacts, used in audio applications for unbalanced signals

TRS jack: 3 pins, used in audio applications for balanced stereo or mono signals (also known as a stereo jack)

TRRS jack: 4 contacts, used for stereo signals plus a microphone or video channels, switches, etc.

TRRRS jack: 5-pin, used in some portable devices with dual microphones or balanced stereo output, etc.
