Rotatable electrical plug

A rotatable electrical plug comprising:

• a non-rotating assembly configured for receiving and being coupled with power lines of the rotatable electrical plug, the non-rotating assembly comprising a substrate, a first ring-shaped conductor and a second ring-shaped conductor spaced from the first ring-shaped conductor, wherein the first ring-shaped conductor and the second ring-shaped conductor are located in concentric circles;
• and
• a rotating assembly being rotatable relative to the non-rotating assembly, the rotating assembly comprising at least two electrode terminals configured to electrically plug-in a power socket;
• a first rotating conductor and a second rotating conductor connected to the first ring-shaped conductor and the second ring-shaped conductor respectively, at least one of the first rotating conductor and the second rotating conductor comprising a base and two arms extending from the base and extending in two non-parallel directions, each of the two arms including a contacting portion, wherein the contacting portions of the two arms contact two different positions of a same ring-shaped conductor of the first and the second ring-shaped conductors,
• wherein each of the at least two electrode terminals is connected to a corresponding one of the first and the second ring-shaped conductors via a corresponding one of the first and the second rotating conductors,
• wherein the rotating assembly further comprises a plate and a fastening element mounted on the plate, the fastening element comprises notches corresponding to the arms and a spacer formed between two adjacent notches arranged in a circumferential direction, the arms is exposed to the exterior via the corresponding notch, and the spacer is disposed on the base.
