Do you have a surge protector in your house? This is the extension cord that has a switch with a corresponding socket. When you plug the appliance, all you need to do is to turn on or off the switch so there’s no need to unplug. Remember that a plugged appliance uses electricity. Take for example the microwave, it has a digital timer that is always visible because it consumes electricity. When unplugged, the panel shows nothing, right? That’s the same with other appliances. With a surge protector, use the switch for convenience and save yourself from the hassle of unplugging.
