Abstract
A night light includes a fixed part, a rotatable part and a shaft connecting the rotatable part and the fixed part and allowing the rotatable part to rotate relative to the fixed part. The fixed part includes two pins configured for electrically connecting with an external power socket, and two elastic elements fixed to top ends of the two pins, respectively. The rotatable part includes two concentric annular conductive members exposed at a lower end of the rotatable part. The two elastic elements provide upward elastic support to the two concentric annular conductive members, respectively, such that the elastic elements can constantly contact and press the two concentric annular conductive members when the rotatable part rotates relative to the fixed part.
