Abstract

See full text

A keyboard device includes a casing, a circuit board, plural keys and an electrostatic conduction module. The circuit board is disposed within the casing. The circuit board includes a ground terminal. The plural keys installed in the corresponding key slots of the casing. The electrostatic conduction module includes a first conductive element, an elastic conductive element and a second conductive element. The first conductive element is installed on a keycap of the key. The elastic conductive element is disposed within the casing and contacted with the circuit board. The second conductive element is connected between the first conductive element and the elastic conductive element. Moreover, electrostatic charges on the keycap are transferred to the circuit board through the first conductive element, the second conductive element and the elastic conductive element and discharged from the ground terminal of the circuit board.
