Abstract
The present invention relates to a keyboard switch which comprises first and second elements alternately engaged with each other and supporting a keycap at the top ends of the elements. The inner edges of the first and second elements are each respectively provided with a corresponding pressing board. The external edges of the first and second elements are provided with a corresponding protruded shaft and a slot to enable restricted movement. When the keycap is pressed at any position, due to the restricted movement, the keycap will move downwardly with a well balanced and stable motion along a shortest distance path to trigger the electrical contact assembly located below when the keycap; when the keycap is released, it will be restored to its original position as a result of a force exerted by an elastic rubber pad mounted within a keyseat.
