Abstract: A touch panel switch system, including an upper assembly, a lower assembly, and a suspension assembly. The upper assembly includes a top cover and an inner support. The top cover and the inner support are fixedly connected to each other. The lower assembly includes a housing and a bottom cover. The top cover and the housing are movably connected to each other. The housing is fixedly connected to the bottom cover. The suspension assembly is connected between the upper assembly and the lower assembly. The suspension assembly effects a trigger stroke in a Z direction. The trigger stroke is at micron scale. Also disclosed is a steering wheel. In the present invention, the trigger stroke is at micron scale, so that the touch panel switch system achieves both touch elasticity and rigidity. Therefore, when the touch panel switch system is triggered, a certain trigger feedback is provided.
