An L-shaped key device includes a substrate, a thin-film circuit board disposed on the substrate, an elastomer disposed on the thin-film circuit board, a keycap shaped like an inverted L at the top of the elastomer, and a scissor-switch module located between the substrate and the keycap. The scissor-switch module includes a first support, a second support, and a third support. The first support is pivotally connected to the substrate and the keycap, and has a front receiving hole and a rear receiving hole. The second support is located within the front receiving hole and is rotatable about a first axis; the second support is inverted T-shaped and has a left top block pivotally connected to the keycap and a right bottom block pivotally connected to the substrate. The third support is located within the rear receiving hole and is rotatable about a second axis; the third support is pivotally connected to the substrate and the keycap. The structure of the scissor-switch module provides good support for the keycap, saving assembly time and reducing assembly costs.
