I followed the instructions on the video for the external switch replacement. Closer inspection revealed it was the actual power switch inside. I ordered it from Ereplacement Parts. Replacing it was self-evident with the grinder internals exposed. A standard head screwdriver & needlenose pliers are the only necessary tools. A magnetic dog dish to hold removed screws is helpful.
