No load switches work as disconnectors, change over switches and earthing switches of traction circuits. Switches may combine all functions together (e.g. earthing switch with change-over switch or with disconnecting switch). Modular design allows to set up multipole switch and could be equipped by lock systems to form a part of safety procedure. Installation could be in boxes under the vehicle frame, on the roof or inside the vehicle. No load switches can be operated manually or by electric or pneumatic drive.
