Abstract: A switch device has a conventional fuseless breaker device, a first conductive blade, a second conductive blade, a fixed plate, and a movable plate. The breaker device has a metal bar having two expansion coefficients, an insulator plate, a safety button, and a coiled spring. The metal bar contacts the first conductive blade. A pressing button which is disposed on the switch device has a first portion and a second portion. A lamp assembly is disposed in the pressing button. The lamp assembly has a break display lamp and a dark display lamp. The break display lamp is disposed in the first portion of the pressing button. The dark display lamp is disposed in the second portion of the pressing button.

Abstract: 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.
