Package Content:
1 x DC Motor Speed Control Switch

Notes:
1. It should be connected with DC voltage, do not connect with AC voltage(e.g. 220V AC). 
2. The anode and the cathode of DC power cannot be connected reversely, otherwise the controller will be damaged. 
3. When running direction is inconsistent with your desire, you can change it by adjusting the linear order. 
4. Potentiometer switch can change the output duty cycle of controller and then change the motor speed.
