When a miner or maintenance engineer is repairing a switching power supply, if they conduct a power-on test before the fault is eliminated or before they understand the fault, or if they power on again before the fault is completely eliminated after replacing parts, the components may be damaged at best, or the fault may be expanded again at worst. Using this protection switch can effectively avoid losses caused by the recurrence of faults, and can visually display whether there is a short circuit, protecting the circuit from damage.

Attention: Please select the power cord plug when purchasing this product. We will give you an International universal socket adapter for free according to your choice.
