Abstract

The invention provides a button structure, which includes a button cap, a trigger element, a scissors-type connection element with a protruding part, a switch circuit board, a support plate and an elastic sheet structure. The elastic sheet structure is fixed on the support plate and is close to the protrusion. When the key cap is pressed, the scissors-type connecting element acts to move the key cap to push against the trigger element, and the trigger element triggers the membrane switch circuit. On the other hand, the protruding part pushes against the elastic sheet structure as the key cap moves, so that the elastic sheet structure collides with the support plate to generate sound.

Description

technical field [0001] The invention relates to a button structure, in particular to a button structure utilizing scissor-type connecting elements. Background technique [0002] Common computer peripheral input devices include a mouse, a keyboard, and a trackball. The keyboard can directly input text and symbols to the computer, so it is highly valued by users and input device manufacturers. Among them, the more common one is a keyboard that includes a scissor-type connecting element. [0003] Next, the architecture of the key structure in the keyboard including the scissor-type connection elements is described. see figure 1 , which is a schematic cross-sectional side view of a known button structure. The known button structure 1 includes a button cap 11, a scissors-type connecting element 12, an elastic rubber body 13, a membrane switch circuit 14, and a bottom plate 15, and the bottom plate 15 is used to carry the second key cap 11, the scissors-type connecting element ...
