Abstract
A keyswitch device includes a cap, a board, a first returning member, and a second returning member. The board is disposed opposite to the cap. The first returning member is disposed between the cap and the board and includes a magnet member and a magnetic member for providing a magnetic force. The second returning member is disposed between the cap and the board for providing an elastic force. When the cap is released at a lowest position, the cap moves upward via the elastic member and then arrives and stays at a highest position via the magnetic force.
