[Prior Art] In order to simplify the design of the button structure of the conventional consumer electronic product, it is advantageous to use an elastic restoring force so that when a button is pressed, the pressed button can be restored to an initial position by the elastic restoring force. The conventional button structure can utilize a single pair of cantilevers composed of an elastic material, one end of each cantilever is attached to the button and the other end is fixed to the other structural member such as by heat fusion. When the button is pressed, the cantilever can stretch its length by elastic deformation so that the button can be depressed to trigger a switch to emit a control signal. When the pressure pressed against the button is released, the cantilever is used to provide an elastic restoring force on the button to cause the button to be retracted to an initial position when it is not pressed. However, by elastically deforming the cantilever to provide the elastic restoring force of the button, it is easy to cause the position of the button to be offset in the pressed and released state due to the difference between the different cantilevers. In addition, the cantilever is heated to other structural parts, so that the second can not be processed and used; the design of multiple pairs of cantilever is more powerful when the cantilever is extended or retracted. In addition, the traditional button structure can be set between the button and the switch. This method can avoid the offset of the button position 4 1380334 during being pressed and released. However, the button structure needs to be It costs a lot of manufacturing costs and is more complicated to disassemble. Therefore, how to design a button structure that can effectively avoid the offset of the button during the pressing stroke, and that is easy to assemble and disassemble, and saves assembly time and assembly cost is an important task for the current electronics industry.
