Yes, simple and it works!
These show up almost every Christmas in hardware stores for Christmas tree lights. I bought several a few years ago and use them for a host of things including outdoor electronics when camping. I started out using them to turn off Christmas tree lights, but I'm always finding stuff that need to be unplugged to turn off & this solves the issue.
