The switch module of the distribution box refers to

A switchboard is a component of an electrical distribution system which divides an electrical power feed into branch circuits while providing a protective circuit breaker or fuse for each circuit in a common enclosure. These points ensure a secure and proper electrical connection, allowing the flow of current to pass safely through to the circuits. Outgoing feeders from a primary distribution substa-tion are typically feeding secondary distribution substations and bigger, most often industrial type, consumers.
