Say what a smart plug does
Switch a lamp on from your chair.
A smart plug sits between the wall socket and a lamp. It cuts or restores the power when your phone tells it to.
The lamp stays an ordinary lamp. Its own switch has to be left on.
Key points
- A smart plug turns the power at one socket on and off
- Whatever is plugged in must be left switched on itself
What to remember
- The plug controls the socket.
- A smart plug switches the socket, not the lamp.
Try this
Look at a lamp you use every evening. Its own switch would have to stay on.
