GAP makes it possible to completely eradicate potential safety hazard to children caused by socket. GAP could realize the function of connection and interruption of power supply in the way of inserting and extracting plug to set internal movable axis in motion. When inserting plug into GAP, axis will be carried forward and the internal sheet metal touch each other, it becoming conductive. When extracting plug from GAP, axis will be pulled out and the internal sheet metal is separated, achieving interruption of power supply. You wont be afraid that children touch the vacant power socket any more.
