When we use a traditional power strip, we need to press the button before it’s connected to the electricity. However, when we use this power-saving strip, we can directly insert the plug into the socket, then the switch is touched and the electricity is on. Once the plug is extracted, the switch will automatically pop out. It saves power and ensures safety.
