Claims

[Claims for Utility Model Registration] 1. A switch element disposed within a case, a key stem slidably guided with respect to the case, and a key stem provided at the lower end of the key stem to press the switch element. A keyboard switch having a pressing portion, a click arm that is interlocked and connected to a key stem within the case and has an engagement protrusion formed on an upper end that protrudes outside the case; and a click arm that engages with the engagement protrusion of the click arm. What is claimed is: 1. A keyboard switch with a click, characterized in that it has a guiding convex portion and a feeling block provided at a position of the case facing the click arm. 2. A clickable keyboard switch according to claim 1, wherein said feeling block is detachably attached to a fitting groove formed on the outside of said case. 3. A keyboard switch with a click according to claim 2, wherein said click arm and key stem are integrally formed of resin.
