Abstract (en)
[origin: EP2573785A1] The short-circuit (1) has mechanical coupling devices (50, 53) coupling movable contacts (61-63) to a pyrotechnical actuator (7) and driving the movable contacts from an open position to a closed position of the short-circuit under propelling action of the pyrotechnical actuator. A waiting zone (92) for the movable contacts is provided on a level located between terminals (2, 3). One of the movable contacts is positioned in the waiting space when the other movable contact is in the open position.
