Instruction input device

Abstract

An instruction input device contains a baseboard having a set of pivot-jointing portions formed with two correspondent pivot holes for penetratingly disposing a shaft with a free end assembled and jointed to an instruction output switch. A flexible layer is assembled and jointed on surface of the shaft, and a coaxial force-bearing layer is further overlapped onto the flexible layer, wherein an instruction actuation switch is disposed on the baseboard at a proper position within reachable action range of the force-bearing layer. By applying the abovesaid simplified architecture, a mouse or a notebook computer with reduced weight, thickness, and size in a relatively lower cost is achievable.
