Intelligent electrical devices

The invention claims a power apparatus (e.g. this) are capable of realizing the current conductive function and capable of realizing man-machine interface of a special chip or a circuit. To the invention, the human-machine interface can function, a pad and carbon paint film switch or weak-current opening of the weak-current control signal. Here the weak-current switch and beforehand a switch compares, and is smaller, and, reliable with low cost, and easy; the anti-corrosive and said of not easy oxidation. Additionally, according to the invention, wherein a man-machine interface of the micro chip is connected with the intelligent method for controlling current conductive switch, the received with the substantial costs and strengthened the reliability. To the embodiment, at the same time the invention can also provides is connected to form a power supply (e.g battery.) adopts atmege16l chip or a circuit, a similarly of the intelligent control. Therefore, formerly intelligent degrees are not equal part functions of high power device; and delay switch, brightness reduced; the time delay automatic shut-off and discontinual starting, wherein the invention, capable of similar. All embodiment of this invention, the creative micro chip or a circuit capable of through the periphery of current of switch, providing a opening groove and is a sequence; the same time, the sequences a groove of the operating while with with a. Or their unit according to sequence code, or unit of the primary switch vibration and time delay automatic shut-off function and brightness of the function, providing power energy strength indication and unceasing current periodically in turn to lengthen the service life of switch and battery equal. The notch is for selecting of function by the control switch and starting.
