If you own an Apple laptop or know someone who does, you’ve seen the breakaway, magnetic connector for the power plug that plugs into the computer. It’s called MagSafe. That was inspired by similar cords used on deep fryers and similar hot appliances, so a passerby would pull the cord out of the appliance, not pull it (and it’s hot contents) off of the counter. It’s saved many a laptop.
Stanley, the company known for it’s home improvement tools, now offers the “Safety Socket”, to allow any plug to now have that kind of safety. Now instead of pulling a cord off of a wall or worse, pulling a plugged in device off of a desk or counter, often injuring the person and damaging the device. They’re just now making their way into retailers, at about $20 each.
