2. The switch is at the tail, the switch function bearing switch is the switch function, and the light switch is the dimming function.
 
II. Circuit board instructions
1 torch adopts advanced constant voltage and constant current technology, which can effectively solve the requirement of constant voltage and constant current for LED torch.
2. Special tips: a. Do not use it over pressure, and the voltage should not exceed 4.2V B. The battery is facing forward, do not set it in reverse, otherwise it will burn plate c. Pay attention to controlling the change of flashlight temperature to ensure heat dissipation d. Do not open the circuit board for non-professionals.
