    Abstract: A key device includes a casing having a base plate and a frame disposed on the base plate, and a key cap having a press plate and a limiter. The press plate is disposed between the frame and the base plate and exposed from an opening of the frame. The press plate has a pivotal side connected pivotally to the frame or base plate and is movable between unpressed and pressed positions. The limiter is disposed at or near a non-pivotal side of the press plate opposite to the pivotal side and engageable with the base plate or frame to prevent the non-pivotal side from escaping out of the casing. A resilient unit is disposed on the base plate to bias the press plate to the unpressed position.

    Abstract translation: 关键装置包括具有基板和设置在基板上的框架的壳体和具有压板和限制器的键帽。 压板设置在框架和基板之间并且从框架的开口露出。 压板具有枢转地连接到框架或基板的枢转侧,并且可在未压制和按压位置之间移动。 限位器设置在压板的与枢转侧相对的非枢转侧或其附近,并与基板或框架接合,以防止非枢转侧从壳体中逸出。 弹性单元设置在基板上以将压板偏压到未压紧位置。
