Abstract: A keyboard includes a substrate, a display member, and a keyswitch assembly. The display member is disposed over the substrate. The keyswitch assembly includes a keycap, a fixing element, two balance bars, and a position-returning member. The keycap is located over the substrate and has a light-transmitting portion located over the display member. The fixing element is disposed on the substrate and has a retaining slot. Each of the balance bars includes a rod portion and an end portion. The rod portion is rotatably engaged with the keycap. The end portion is movably retained in the retaining slot. The position-returning member abuts against the keycap above the substrate and is adjacent to an edge of the keycap.

Abstract: A keyswitch device includes a connecting member and a keycap. The connecting member has an engaging shaft. The keycap includes a pressing body and a shaft hole structure. The pressing body has a bottom surface. The shaft hole structure is connected to the bottom surface and has an engaging trough and an inlet passage communicated with each other. The engaging shaft is rotatably engaged in the engaging trough. The inlet passage has a first inner wall and a second inner wall opposite and parallel to each other. The first inner wall and the second inner wall are inclined relative to the bottom surface of the pressing body.

Abstract: The invention provides a method for rapidly detecting a pathogen in animals or plants comprising using a specific primer set and nucleic acid in a sample to carry on a loop-mediated isothermal amplification. If at least one amplification occurs, the sample comprises the pathogen. The invention also provides a primer set, probe and kit for detecting a pathogen in animals or plants.
