Indoor change-over switch BW

With its modular linear construction, the BW series can accommodate a variable number of moving contacts and high voltage terminals (HVn), enabling a wide range of configurations and applications. It is installed inside vehicles, either in upright or horizontal position, and is used to select/change the configuration of traction or/and auxiliary circuits. The BWT type has two vertical rows with up to 24 terminals, while the BWU with 4 vertical rows counts up to 56 terminals. The device is electro-pneumatically or electrically controlled, and can also be operated manually during maintenance operations.
