On load changeover switch is an electrical switch that is used to switch electrical loads from one source to another. It is used to switch between different sources of power, such as an AC power source, a DC power source, or a combination of both. The switch can also be used to switch between different types of loads, such as resistive, inductive, and capacitive loads. In some cases, the switch can also be used to switch between different types of loads and different sources of power. The load changeover switch is commonly used in industrial applications and is designed to be reliable and durable.
