Abstract
A key array structure comprises a key array constituted by connecting a plurality of key members arranged in an array, it is characterized in that an elastic element is connected between each two adjacent key members and a positioning hole or position holes is or are disposed in the key member. The elastic member disposed between each two adjacent key members of the key array structure according to the present invention has a cushioning effect to adjust the deformation of the key array caused from the processes such as heat baking while manufacturing so as to allow the positioning hole in each key member to be precisely positioned with a corresponding position pin on a relative member.
