ABSTRACT:
A control switch includes a rotary shaft rotatably mounted therein. A switching knob is mounted to the rotary shaft and a surface of the control switch. Also, a stationary shaft is arranged beside the rotary shaft. A driving control disk and a locking control disk are sequentially and rotatably fit onto the stationary shaft so that when the switching knob on the surface is actuated, the rotary shaft is rotated to selectively drive cables through the driving control disk or the locking control disk to thereby effect switching of transmission modes and the function of locking. Thus, the amount of space required for installation is reduced and the chance of malfunctioning is also reduced and further, the costs are reduced.
