CONSTITUTION: A rotation-activated electric component includes a communication unit, a power source(112), a component(116), and a switch(114). The communication unit is adapted to interact with an external device. The component is adapted to process first information from the communication unit and transmit second information for the external device. A switch performs the communication through the communication unit in a preset rotation speed. |
