I was very happy to find this part at such a great price here at Revain. This was exactly the part I needed for my broken Dyson DC25 Ball vacuum switch. Basically, the vacuum didn't turn itself off, and the only way to do it was to unplug it. This part was the solution to that! Unfortunately, I couldn't find a video anywhere on how to replace this part. So I made this one which I hope will help someone how to make it. I forgot to add in the video that before starting the canister is removed and the extension hose pulled up and away from the machine and then laid on the ground. The extension hose does not need to get in the way to reach the screws that can be used to remove the panel. Disclaimer ---- I am not a Dyson authorized repair technician. I made this video just as a guide to other shadow tree mechanics.
