Just what I needed to replace the same mogul socket in a very old standing on the floor lamp. The former one had failed internally with crumbling plastic in the 3-way switch after about ten years. The new one is a different Chinese manufacturer, so I hope it lasts a longer time. Tip: Save the screws from the original installation like I did. Two mounting screws going down through the socket had slightly different threading than the new ones from LightBulbs.com, so I used the previous two from the former installation, I didn't need the pipe-like stub underneath the socket at all.
