Embodiment Construction
[0031] Below in conjunction with accompanying drawing, the present invention will be further described:
[0032] In the present invention, a coil is wound on a soft magnetic core, and a set of components composed of a magnet and two armatures is placed at each end, and when the beam steel frame rotates around the axis, the armature can be made to contact different surfaces of the iron core and A sudden change of N and S poles occurs, resulting in a sudden change in the direction of the magnetic field lines in the iron core and an induced electromotive force. When the user presses the outer button cover with a finger, the leaf spring elastically deforms under the action of the armature and the iron core to accumulate potential energy. An armature is attracted to the corresponding surface of the iron core. The present invention is an improvement based on patent 201420267207.0, and the specific realization principles of A steady state and B steady state will not be repeated here...
