An air switch is a type of circuit breaker; its internal structure is somewhat more complex, comprising main contacts, springs, bimetallic strips, heating elements, and a low-voltage release lever, among other components. In the case of an isolating switch, its structure mainly consists of conductive parts, as well as a base, frame, control mechanism, etc.
