This is the kind of 1/4" stereo jack you might find in home stereos and PA systems. Switched contacts allow you to detect whether or not there is something plugged in to the jack. The jack can be panel mounted in an 11mm diameter hole.
The jack comes with a plastic washer and nut for panel mounting.

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

The spring contacts look to be better laid out and more reliable than the free floating fully exposed spring ones you see in other/older models. I cant say I like the plastic mounting bezel very much though. One, it doesn't match any other mounting bezels for most any other switch or encoder out there in style, two its plastic in one of probably the most heavily torqued items you would panel mount at all. If it weren't for the ability to mount via holes in the breakout board they also offer then I would have probably bought a different model. The breakout board for this item really saves it.

Is there an SVG file for fritzing? I designed a PCB with the one in the library and the one I received doesn't fit.
Sadly we don't have anything for this part in Fritzing, but it is in our Eagle library. You might be able to convert the Eagle part to a Fritzing part if you can find a converter utility somewhere.
I am looking in the eagle libraries and can not find this item. Would someone please help me out?
It is now in SparkFun-Connectors.lbr, as component AUDIO-JACK4-.25-HORIZ-TRS.
Which of these leads is T, R, and S? I'm having trouble reading the datasheet (my eyes aren't as sharp as they used to be).
If you're looking at the jack from the panel-mount end (the side with the threads and nut), and the legs are pointing downwards, it goes like this:
The right hand set of pins are the connections.
The left set of pins are the normals, in the same order: sleeve nearest the panel, then ring, then tip.
When no plug is inserted, the each normal ties to it's corresponding connection (Tip->tip normal, ring->ring normal, sleeve->sleeve normal). When the plug is inserted, these connections are broken. The connections are then tied to the signals in the jack, and the normals are left floating.
Is this breadboard/veroboard friendly?
Answering my own question: no they aren't.
Sorry it's taken so long, but it is now breadboard friendly:

No problem. Great to know about the breakout!
