Patent ID: 8425105

Claim:
A nightlight comprising: a body having a press button, said body including at least one displaceable coupling member exposed therethrough; a base arranged on said body and having a round engagement basin at a central region thereof; a rotatable plug arranged between said body and said base and including a round positioning engagement block arranged on a front side thereof and two conductive insert plates penetrating said round positioning engagement block, said rotatable plug including a conductive member defining a plurality of coupling portions offset one from the other in angular position about a rotation axis; wherein said round positioning engagement block is moveably installed in said round engagement basin to enable said rotatable plug to rotate about the rotation axis with respect to said base between a plurality of releasably locked angular positions, said rotatable plug at each said angular position being releasably locked by one of said coupling portions thereof engaging said coupling member in resiliently biased manner; and a light emitting element arranged in said body, wherein said press button is used to control a conduction state of said light emitting element and said conductive insert plates.
