Because the switch offers deeper infrastructure: connecting multiple banks/acquirers, managing switching logic, multi-channel support, settlement & reconciliation, performance optimisation and redundancy for high volume operations. It is typically used by financial institutions and large merchants rather than basic merchant gateway use-cases
