Keyboard switch with guide core limiting function

Abstract

The invention discloses a keyboard switch including a base, a cover covering the base to form a cavity, an upper guide core disposed in the cavity and an upper guide core limiting mechanism including a lower guide core elastomer, a lower guide core, a middle guide core spring and a middle guide core sequentially disposed on the base. The upper guide core and the middle guide core are connected through an upper guide core spring. The keyboard switch of the invention provides accuracy of the press-conduction displacement, accurate positioning of the conduction course, and adjustability of the press force, such that the press force becomes more balanced, and the keyboard switch is conducted when the guide core is pressed downwards. Thus, the overall press stability of the keyboard switch is improved.
