So what are high current switches and what are they used for? High-current switches are specialized electromechanical devices that are capable of handling significant electrical currents while connecting or disconnecting a power source from a load.
They play a crucial role in managing high currents while also protecting circuits from damage. They’re used across a multitude of industries (industrial, medical, transportation, agricultural, etc.) and have a variety of practical applications.
