High quality double power source auto-switch hot sale in China

 Double power source auto switch  

The double power source auto switch can switch to normal power or reserve power automatically. When a voltage disturbance or phase loss is detected, the power switching device will automatically connect one or several load circuits from one power source to another. The switching requires no human intervention, so that your line of production will not be called off, reducing economical damage caused by the power supply issues. With fewer screws included comparing to the older models, this new switch also reduces electrical hook-up and labor time.
