摘要： A key switch adapted to raise or lower a key top according to need is disclosed. The key switch includes a key top, a link assembly comprised of two link members and operatively connected to the key top, which is retracted by a pressure on the key top and extended by release of the pressure and which has an elastic member at its lower end, an FPC placed on a frame of a keyboard to recognize pressing of the key top, and a plate movably placed on the FPC, to which a lower end of one of the link members is connected, and which has an elastic supporting member being in contact with the elastic member of the link assembly. When the key top is pressed down, the link assembly is retracted while compressing the elastic member of the link assembly and the elastic supporting member of the plate. When the link assembly is further lowered, an elastic resistance of the elastic supporting member is suddenly increased, and thus the elastic member of the first link member is suddenly bent and quickly lowered, thereby affording a click sense to a user and enabling the bent portion of the elastic member to press the FPC.

摘要： The key switch includes a key, a linkage assembly having first and second linking members with arms connected to outer ends thereof, and a bow-shaped elastic object connected between the arms, which is lowered and raised with the key, the first and second linking members including a coupling recess and a coupling protrusion and inner end thereof and hinge protrusions at side surfaces thereof, the coupling recess and protrusion being engaged with each other to constitute a linkage rotating shaft, a frame including hinge hooks engaged with the hinge protrusions, and an FPC placed on the frame for operation by contact with the linkage assembly. As the key is operated, the arms rotated downward while the linkage rotating shaft rises, and the elastic object gradually flattens and then bends into an upwardly convex bow shape, thereby providing a clicking sensation and a restoring force to the linkage assembly.
摘要翻译：钥匙开关包括钥匙，连杆组件具有连接到其外端的臂的第一连接件和第二连接件以及连接在臂之间的弓形弹性物体，该弹性物体用钥匙下降并升高，第一和第二连杆构件，其包括联接凹部和联接突起及其内端以及在其侧表面处的铰链突起，所述联接凹部和突起彼此接合以构成联动旋转轴，包括与所述铰链突起接合的铰链钩的框架，以及通过与连杆组件接触而放置在框架上用于操作的FPC。随着钥匙的操作，当连杆旋转轴上升时，臂向下转动，弹性物体逐渐变平，然后弯曲成向上凸起的弓形状，从而为连杆组件提供咔哒声和恢复力。

摘要： Disclosed is a key switch comprising a key top for receiving pressure from a user's finger, a link for lowering the key top when pressure is applied to the key top and pushing the key top upwardly when the pressure is released, and a flexible printed circuit (FPC) provided on an upper surface of a keyboard frame for recognizing the key action by a pressing-contact of the link therewith. The link has first and second legs pivot-coupled with each other, a return plate spring applying a returning force to the key top, and a contact plate spring coming into pressing-contact with the FPC. The key switch has a simple structure and imparts a sufficient clicking sensation.
