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.

A keyswitch device comprising:
- a cap;
- a board disposed opposite to the cap;
- a first returning member disposed between the cap and the board, the first returning member comprising a magnet member and a magnetic member for providing a magnetic force;
- and
- a second returning member disposed between the cap and the board for providing an elastic force, the magnet member being spaced apart from the magnetic member at a maximum distance when deformation of the second returning member reaches to a maximum value;
- wherein when the cap is released at a lowest position, the cap moves upward via the elastic force and then arrives and stays at a highest position via the magnetic force.
