Abstract
A keyboard device includes a base plate, a circuit board and plural keys. Each key includes a keycap, a scissors member, a restoring element and a sensor. The scissors member is connected with the keycap and the base plate. The restoring element is arranged between the keycap and the base plate and electrically connected with the circuit board. When the restoring element receives electricity, the restoring element is subjected to deformation and the keycap is correspondingly moved away from the base plate. When the keycap is depressed and close to the base plate, the restoring element is pressed by the keycap to trigger the sensor to generate the key signal. When the keycap is no longer depressed, the keycap is driven by the restoring element so as to be moved away from the base plate.
