Abstract:
1. A high or medium voltage switch, comprising: a first and a second terminal; a switching assembly having a first and a second configuration, wherein in said first configuration, said switching assembly forms at least one conducting path between said terminals and wherein in said second configuration said switching assembly does not form a conducting path between said terminals; at least one drive for moving said switching assembly at least one of from said first configuration to said second configuration and from said second configuration to said first configuration, wherein said at least one drive comprises an at least partially conductive plunger movable along a displacement direction between a first and a second location and connected to said switching assembly; a plurality of actuator rods arranged in a row or rectangular matrix and connected to said plunger via an adapter member, wherein the plunger and adapter member are enclosed in a frame having an opening through which at least the plurality of actuator rods extend; at least one non-circular drive coil positioned adjacent to said plunger; and a current pulse generator adapted to generate a current pulse in said at least one drive coil for driving said plunger away from said at least one drive coil.
