Abstract: A key structure is provided. The present key structure includes a key cap, a scissor-type frame, an elastic contact body, a membrane circuit board, and a bottom board. A plurality of flanges is provided on the bottom of the elastic contact body, with the surface of the flange being formed as an embossed surface having a cross-striped structure. A print layer is provided on the area of the membrane circuit board corresponding to the flanges of the bottom of the elastic contact body, such that there is a height difference between the print layer and the membrane circuit board. The print layer is formed of a plurality of discontinuous printing portions between which a plurality of holes is formed. After the elastic contact body is bonded to the membrane circuit board by an adhesive, the press force of the elastic contact body caused by pressing the key can be released via the holes. The bonding area of the bottom of the elastic contact body is increased by the cross-striped structure of the embossed surface so as to enhance bonding between the elastic contact body and the membrane circuit board and prevent the adhesive from being extruded out from therebetween.

Abstract: A keyboard with liquid-draining function, at least including: keys, elastic body layer, circuit board layer, bottom board and sealing layer; wherein the bottom board is installed with at least a liquid-draining hole, with the dividing mechanism being installed between the circuit board layer and the bottom board to form a liquid-draining space. The liquid-draining space and the liquid-draining hole are connected for the purpose of draining liquid that is accidentally poured into the keyboard, so that liquid flowing down through the keys can be drained away swiftly via the liquid-draining space and drained out of the keyboard through the liquid-draining hole, thus preventing liquid from accumulating in the keyboard, and maintaining the normal operation of the keyboard.
