Abstract
A keyboard device includes a base plate, a key and a membrane circuit board. The key is connected with the base plate. The membrane circuit board is arranged between the key and the base plate. The base plate includes a connecting structure. The connecting structure is protruded upwardly and penetrated through the membrane circuit board. The key includes a keycap and a stabilizer bar. The stabilizer bar is pivotally coupled to the keycap. A hook part of the stabilizer bar is penetrated through a corresponding locking hole of the connecting structure. The membrane circuit board includes an extension part. The extension part is extended from a first side of the locking hole to a second side of the locking hole and penetrated through the locking hole. Consequently, the hook part of the stabilizer bar is movable on the extension part of the membrane circuit board.
