  • a baseboard having a pair of pivot-jointing portions disposed at proper positions thereon and formed with two correspondent pivot holes, wherein a shaft having a free end assembled and jointed with an instruction output switch is penetratingly mounted in said pivot holes;

    a flexible layer assembled and jointed with said shaft on its outer circular face;

    a force-bearing layer made of a material harder than said flexible layer assembled and jointed on said flexible layer at its outer circular face; and

    an instruction actuation switch assembled and disposed at a position within reachable action range of said force-bearing layer;

    wherein said force-bearing layer is pressed to drive said flexible layer to actuate the instruction output switch at one end of said shaft to effect an output signal; and

    said flexible layer softer than said shaft and said force-bearing layer, said flexible layer is squeezed to push said force-bearing layer to in turn press said instruction actuation switch to effect an output signal.
