Abstract: A soft break switch for forming a short circuit between two conductors while the switch is in a closed position, for forming an increasingly resistive circuit between the conductors while the switch is being moved to an open position, and for forming an open circuit between the conductors when the switch is in an open position. The resistive circuit enhances arc suppression.

Abstract: Apparatus defining an electrical connection capable of carrying relatively high electrical currents including a number of heavy-duty electrical conductors normally spaced apart and electrically interconnected by an improved connector unit having a plurality of spaced, stacked plates having louvered electrical connector devices. Each plate has a pair of opposed faces with each face having one or more grooves therein. Each groove is provided with one of the louvered electrical connector devices. Each such device has a plurality of spaced, electrically conducting, resiliently mounted fins whose curved outer edges are adapted to engage the corresponding plate and to make electrical contact with the adjacent electrical conductor. A number of embodiments of the apparatus are disclosed.
