ABSTRACT:
The invention is a switch for use with very high currents and relatively voltages. The contacts of the switch comprise several stationary rectangular bus bars positioned parallel to each other and one or more movable bus bars which slide along the surface formed by the stationary bus bars and conduct current from one stationary bus bar to another. Attached to each movable bus bar are several louvered contact strips which establish a large number of electrical contacts between the movable and stationary bus bars and conduct all of the current which flows between them. Electrical circuits through the switch are turned on and off by changing the positions of the movable bus bars. The positions of the movable bus bars are changed using a screw drive mechanism which is driven by an electric motor.
