Product review (4 stars): Decent replacement but could be a bit better.
The lid switch recently died on our 10 year old Kenmore washer. I didn't find out until I went to change a load over to the dryer only to find the washer was still full of dirty water. We eventually figured out it was the switch. I looked it up through the Sears website and they listed it for $27 or so and it was available at a local Sears parts store. I decided to try searching on Amazon and found it for $6, so it was kind of a no-brainer. I had to wait 2 days for Prime shipping but I'm okay with that.

Installation on my particular unit was more involved than I expected, since the instructions I was using weren't entirely clear that the ENTIRE top, front, and sides of the washer had to be tilted forwards to access the switch. I got through it eventually, but when I put everything back together and fully tightened the two mounting screws, I found that the switch basically "froze" in such a way that the washer always thought the lid was closed. I loosened the two mounting screws back up a few turns and this released the pressure on the switch so that it could disengage when the lid was lifted. I'm not sure if this is something I could somehow adjust so that it works when the mounting screws are fully inserted, but it works for now so I'm leaving it alone. All in all, it could be a bit better (like, include instructions on how to install and adjust it!) but it gets the job done. Saved $21 over the official switch while I was at it, too.
