Smart Power Outlet
This power switch was designed with a real-life workshop scenario in mind.
The Automatic Power Switch from Craftsman is a power outlet box with three outlets designed to be used simultaneously. A power tool is plugged into the top outlet; accessories to the power tool, such as a vacuum or a light, are plugged into the bottom outlets. When the power tool is turned on, the accessories are automatically activated. When the power tool is turned off, the accessories are shut off as well.
