ABSTRACT:
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.
