ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a lamp assembly which is disposed in a switch device. More particularly, the present invention relates to a lamp assembly which is disposed in an electronic device.
A conventional breaker device is often disposed in a main switch box. However, a plurality of branch switches do not have any conventional breaker device.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a dark display lamp which is disposed in a switch device to be operated while overloading.
Another object of the present invention is to provide a break display lamp which is disposed in a switch device to be discontinued while overloading.
Another object of the present invention is to provide a dark display lamp which is disposed in a plug to be operated while overloading.
Another object of the present invention is to provide a break display lamp which is disposed in a plug to be discontinued while overloading.
Accordingly, a switch device comprises a conventional fuseless breaker device, a first conductive blade, a second conductive blade, a fixed plate, and a movable plate connected to the fixed plate. The breaker device comprises a metal bar having two expansion coefficients, an insulator plate disposed in the switch device, a safety button disposed on a top end of the insulator plate, and a coiled spring disposed on an upper portion of the insulator plate. The metal bar contacts the first conductive blade. A pressing button is disposed on the switch device. The pressing button 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. A pressing pin is disposed in the switch device. A compression spring is disposed in the switch device. A first pin of the break display lamp is connected to the pressing pin and the compression spring. A second pin of the break display lamp is connected to a resistor. A first pin of the dark display lamp is connected to the pressing pin and the compression spring. A second pin of the dark display lamp is connected to the resistor. A third conductive blade is disposed in the switch device. A first connection plate is connected to the resistor. A second connection plate is connected to the resistor. When the pressing button is in the on state, the first connection plate contacts the third conductive blade. The metal bar will be bent and the safety button will be ejected while a current is overloading. The break display lamp will be discontinued. When the pressing button is in the off state, the second connection plate contacts the third conductive blade. The dark display lamp is lightened.
