What is the difference between Open and Closed Circuit Mono Audio Jacks?

Open circuit jacks just have contacts for the sleeve (ground) and the tip.

Closed circuit jacks have those same connections, but also have an internal connection that touches the tip contact inside the jack only if there is no plug inserted. That way, you can connect ground to this extra contact, and it will ground the jack's tip contact when there is no plug in the socket, and therefore keep hum and noise from being picked up.

If you get closed circuit jacks and don't need the shorting capability, just ignore them, not connecting any wires to them and the jack will work just like an open circuit jack. The only difference is that there will be an extra solder lug on the closed jacks.
