Rotatable plug

A rotatable plug comprising:

• an upper cover defining two slots in parallel on the top surface thereof;
• a lower cover mating with the upper cover to form a holding space;
• a mount placed on the lower cover and held in the holding space;
• two conductive terminals disposed on the lower cover;
• a rotatable rack including a pivot, two seats formed on opposite ends of the pivot and two prongs, the pivot being pivotally mounted on the mount, each seat defining a cavity for receiving and securing one end of each prong and a leading opening communicating with the cavity, another end of said prong passing through the corresponding slot and being rotatable around the pivot to be held in the slot;
• two connecting members, one end of each of the members contacting with the corresponding conductive terminals;
• two first conductive elements fixed on the other ends of the respective connecting members, each first conductive element having a first conductive protrusion;
• and
• two second conductive elements, one end of each second conductive element being fixed on the corresponding prong, another end being held in the leading opening of the corresponding seat and rotatably contacting with the conductive protrusion of the corresponding first conductive element.
