The first keycap is liftably disposed on the upper surface and includes a first abutting portion. The second keycap is liftably disposed on the upper surface and includes a second abutting portion. The sliding plate is parallel to the substrate and movable relative to the upper surface along a sliding direction. The sliding plate includes a first guiding member and a second guiding member arranged along the sliding direction. The first guiding member has a first inclined guiding surface, and a first inclined angle is between the first inclined guiding surface and the upper surface. The second guiding member has a second inclined guiding surface, and a second inclined angle different from the first inclined angle is between the second inclined guiding surface and the upper surface.
