The control mechanism for a steering differential device of an electric vehicle includes a touch sensor switch assembled on the fixed shaft sleeve of the head tube on the electric vehicle, with a feeler in a downward configuration state. The electric circuit of the sensor switch is connected with the controller that controls two rear wheels of the electric vehicle. A guiding base, which is set on the top of the wheel carrier lying at the bottom of the head tube and is exactly aligned to the place beneath the sensor switch. Its middle part forms a flat surface, and its left and right ends form the downward bevels, respectively. The sensor foot can exactly touch against the flat surface of the guiding base and the circuit then appears to be closed due to the pressure. The feeler can be aligned to one downward bevel of the guiding base.
