A load switch is a type of switching device positioned between circuit breakers and disconnectors. It features a simple arc extinguishing device capable of interrupting rated load current and certain overload currents, but cannot interrupt short-circuit currents. Load switches can be classified into high-voltage and low-voltage types according to their operating voltage.Solid gas-producing high-voltage load switch: This type utilizes the energy from the breaking arc itself to cause gas-producing
