A toggle switch (also known as a rocker switch) is a manual switch that controls the on-off or switching of a circuit by pulling a protruding toggle handle. The toggle handle is usually in the shape of a boat or a bar, providing a distinct tactile feel when operated. It comes in two-position and three-position types, with some three-position switches adopting a non-positioning design. Toggle switches are widely used in circuit control scenarios for industrial equipment, automobiles, and electronic instruments.
