Every third vacuum main switch in the world is built by Richard AG.

Disconnecting and connecting under load.

The function of the pneumatic main switch is to disconnect the current flow between the overhead contact line and the electrical equipment of the locomotive. Our low-maintenance load switches ensure reliable spark quenching and can be switched in phase-controlled mode.
