ABSTRACT:
A rotatable plug with an arcing resistant mechanism is disclosed which includes an upper cover, a lower cover mating with the upper cover to form a holding space, a mount placed in the holding space, a rotatable rack placed on the mount, a pair of conductive terminals fixed on the lower cover and a pair of connecting slices. The rotatable rack includes a pivot and a pair of prongs, wherein the prongs are fixed on the both ends of the pivot respectively. Each connecting slice connects the corresponding prong of the rotatable rack with the corresponding conductive terminal. Therefore a circuit exists between the prongs and the conductive terminals, so that the rotatable plug with an arcing resistant mechanism can suppress the arcing that is produced between the prongs and the conductive terminals. Thus the rotatable plug with an arcing resistant mechanism is used safely and has a long lifetime.
