The testing machine can be used to click-lineation lifetime on the surface painting hardness of the touch screen and plastic shell or tested the surface hardness and adhesive attraction.It can also test a point’s lifetime with membrane switch,jiggling switch,computer switch and multifunction switch which need to be with clamps.It is more convenient to get the variation curve,times of life-span,surface hardness and painting adhesive attraction of tested product through the analysis of the resistance value got by testing.this machine used magnetic suspension as the dead-weight and eliminated the inertia. It also used the weights for weight.The acceleration and deceleration curve of numerical step motor is considered more particularly than common air-operated testing machine. And it can to be the nice machine for factories to inspect the quality.
