A socket has a hollow base casing, and an upper casing engaging with the hollow base casing. The upper casing has an oblong hole and a pair of slots. The hollow base casing receives a first conductive blade, a second conductive blade, a fixed plate, and a metal bar. A breaker device is disposed between the upper casing and the hollow base casing. A metal bar contacts the first conductive blade. The metal bar will be bent while a current is overloading. Then the metal bar will not contact the first conductive blade. A break display lamp and a resistor are disposed in the upper casing. The break display lamp is connected to the resistor.
