More Information
Summary:A detachable button structure includes a button cap, an actuating member and a compression spring. The button cap includes a plurality of limiting portions separated from each other and defining a receiving area. The actuating member is disposed in the receiving area, and includes an annular portion and an actuating portion protruding from the annular portion. The annular portion abuts and is fixed on an upper surface of each of the limiting portions. A first side of the compression spring sleeves the limiting portion and the annular portion, and is fixed on the limiting portion or the annular portion. A second side of the compression spring directly contacts a thin-film circuit board. In the process of pressing the button cap to drive the actuating portion contact with the thin-film circuit board, the compression spring generates elastic deformation, such that the actuating portion does not make sound due to instant crush.
