The invention relates to the field of actuator mechanisms, and discloses a friction-free all-circumferential flashlight state switching mechanism and method, and the friction-free all-circumferential flashlight state switching mechanism comprises an execution assembly, a manual driving assembly, an electric driving assembly and a switching assembly. A worm gear and a worm are adopted as an execution assembly, and the two ends of the worm are connected with a manual driving assembly and an electric driving assembly through a planet wheel and a clutch respectively. Power can be provided by manual operation when the motor is powered off, the motor is automatically switched to electric operation when the motor is powered on, the structure is compact, and switching can be achieved in the whole circumferential direction; in the operation process, the switching rod does not make contact with the inner wall of the worm shaft and the end face of the planet wheel mechanism, and friction-free switching is achieved.
