What is this "appliance control" power strip?
A quick search came up with this: (Amazon)
The disk is a touchpad which controls dimming of the lights plugged into the strip.
This took me less than one minute, entering &quot;38AF APPLIANCE CONTROL&quot; into Google. (Actually, I didn't type it, I copied it from your question.) In the future, I'd suggest using a web search before posting.
