4 Pole Switch Gear with LED Light

 As a key switching device, we have noticed that in the actual use , if the on-off state of the switch is abnormal, then it will cause a very significant hidden danger for the safety of electricity.

    In the case of high current overload, the switch will melt the contact, at this time even if the switch is turned off, the circuit is not correctly disconnected, and the electrical appliance is still with points. This will cause unimaginable danger to users or maintainers.

So we developed the first generation of indicator switches

1st generation

In this version of the product, a new set of LED lights is added, which requires the user to connect the LED light line with the fire line at the input end. In normal use, LED can display the on-off state of one phase switch. The display of switch state is realized in a preliminary sense. 

However, the disadvantage is that the user needs to manually connect the LED light line with the fire line, and only one of the three phases can be monitored

So, after a redesign, we got a new 4 Pole switch that does not need wiring and detects the three phases at the same time

2nd generation

The switch is updated with a built-in Buck rectifier circuit,There is no need for the user to connect the LED wire in use,Greatly speed up the connection of the switch

The built-in circuit use red,white,bule LDE to monitors the three-phase circuit at the same time, the accuracy of the indication is improved.

Including but not limited to: switch phase missing,not open,not closed,or one of the phase melting and other phenomena
