This mini jack plug features a 1/8-inch (3.5mm) shaft and tip paired with a black insulating handle. Measuring 1 3/4 inches in total length, it is designed for two-conductor (mono/TS) audio connections in vintage headsets, crystal radios, extension cords, and auxiliary equipment interfaces.

The compact overall length provides a slim profile, while the removable threaded handle allows easy access to internal solder lug terminals for wire attachment.
