A motor scooter embodying an improved electric motor driven wheel. An input module IS coupled to the microprocessor, a symbol may be entered into a blank space on a grid displayed on a display coupled to the microprocessor. The normally-open contact is arranged on a normally-open spring contact, which exhibits a higher spring stiffness than the changeover spring and is resiliently deflected in the switching position, and the changeover spring andor the normally-open spring contact comprises a deflection region at least partially surrounded by a weakened zone.
