Keyboard device with electrostatic discharge protection function

A keyboard device with an electrostatic discharge protection function, the keyboard device comprising:

• a casing comprising plural key slots;
• a circuit board disposed within the casing, and comprising a ground terminal;
• plural keys installed in the corresponding key slots, respectively, wherein each key comprises a keycap and a supporting element, and the keycap is installed on the supporting element;
• and
• at least one electrostatic conduction module, wherein each of the at least one electrostatic conduction module comprises a first conductive element, an elastic conductive element and a second conductive element, wherein the first conductive element is installed on the keycap, the elastic conductive element is disposed within the casing and contacted with the circuit board, and the second conductive element is connected between the first conductive element and the elastic conductive element,
• wherein the first conductive element is linked with the keycap, and the first conductive element is moveably connected with an end of the second conductive element away from the elastic conductive element, wherein 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.
