What is an Onload Changeover Switch?
An onload changeover switch is a mechanical switch that has been engineered to switch load between two sources of power—generally between mains and generator or mains and inverter—without cutting off the power supply. It supports live switching, making it suitable for environments where continuity of power is paramount.
The Havells 13947 Part III switch has been engineered according to international standards, providing user safety as well as operational efficiency.
