I bought this connector to use it a home made mini amp for headphones. The pics don`t show, but it has a row of pins on both sides. I have printed my own PCB for it, so i don`t know if the spacing fits a pre-drilled PCB, but i think one could bend them in. When it comes to the connection itself, it`s not much to say. It works, the jack is not hard to plug in or remove, and i have not encountered "dead" positions. The only thing i would like to have is a metal nut; the plastic one looks a bit cheap, but that`s only me :) I`d definitely buy this again if i need such a connector.
