The motor wire can be positive or negative. If the direction of rotation is not as expected, you can adjust the wire sequence or the switch position to change the direction.3.Set the switch.The positive reversing switch is used to control the direction of the motor's speed.When the switch is in the zero position, the motor stops rotating.4. Adjust the potentiometer knob. The potentiometer adjustment knob can change the output duty cycle of the controller, and therefore the motor speed. Package includes: 1 pc x DC motor speed controller
