ABSTRACT:
A keyboard with a wobble prevention structure, which is substantially a substrate having at least one press key arranged thereon while enabling each press key to be driven to move in a reciprocating manner following a specific direction, and having a plurality of position limit devices disposed on the substrate and beneath the periphery of a corresponding press key. In a preferred aspect, each position device is integrally formed with the substrate, or can be formed on the substrate by stamp forming technique, that each is used to confine the corresponding press key to move following only the specific direction, such that the wobbling of the press keys is prevented.
