Abstract

The utility model provides an improved structure of keyboard key-press, essentially consisting of a plurality of key-press sockets, key-presses, and elastic coupled bodies, etc. When in assembling, the utility model is clamped in the key-press sockets by the elasticity of a spring plate of the key-presses and placed under a bump by a convex button so as to lead the key-presses to fix in the key-press sockets and uneasy to fall. When in use, pressure columns and ribs of the key-presses form a leveling pressure surface and are contacted with the top of the elastic coupled bodies, therefore, the elastic coupled bodies are compressed by the pressure columns and ribs of the key-presses and deforms; the coupled bumps are contacted with the contacts on a guide circuit device and the guide circuit that forms the contact sends signals corresponding to the key-press, thus leading the elastic coupled bodies to right locate and not slide and avoiding the elastic coupled bodies being squeezed, crammed and deformed.
