摘要： A scissors-type key switch comprising a key top, a scissors-type supporting bracket, a base member, an elastic actuator, a membrane switch, and a bottom plate is provided. The membrane switch, the elastic actuator, and the base are disposed above the bottom plate. The scissors-type supporting brackets are pivotally supported and received on the base by the pivotally engagement between the pin shaft of the supporting brackets and the connecting holes of the base. The key top is also pivotally connected to the scissors-type supporting brackets by the connecting slots of the key top and the pin shafts of the supporting bracket. This scissors-type key switch features a simplified structure resulted from reduced number of components and durable operation wherein the key top can readily move down and up without rolling thereof. The manufacturing cost is advantageously reduced while the throughput is considerably increased.

摘要： A waterproof keyboard is provided, which has keys, scissor frames, elastic layer bodies, a membrane circuit board, a support plate and a bottom plate, wherein the bottom board is disposed with a plurality of stamped nodes, which are corresponded by apertures disposed on the support plate. The means of riveting is used for riveting the bottom plate and the support plate, such that no apertures can be found on the bottom plate, so as to prevent liquids poured on the keyboard by accident from infiltrating down to the motherboard underneath the bottom plate, thus assuring that the motherboard is not damaged thereby. As a result, the computer can be kept operable. Also the membrane circuit board is mounted on top of the support plate, thus rendering the overall structural assembly easier and such overall structure more stable.
