5. Switch and Pilot Indicator

A central On/Off switch allows the user to cut or restore power to all three sockets at once. This feature improves convenience and energy efficiency, especially when using multiple devices that can be powered down together.

An integrated pilot indicator light clearly shows when the trailing lead is active (i.e., when electricity is flowing through the sockets), which helps avoid confusion or unintended energy use.

6. Cable Length and Flexibility

The 3-meter cable provides generous reach from the wall socket, allowing the unit to be placed in flexible locations, such as under desks, behind entertainment systems, or in workshop areas. The cable is soft yet thick, ensuring both flexibility and durability, with strong insulation for safety.
