Abstract
A reciprocating rod bears a bridge which is movable on the rod with initial movement of the rod in a given direction completing closure of bridge carried moving contacts onto stationary contacts for inserting a resistance in a circuit during closure. Linkage between the rod and main contacts functions to subsequently close the main contacts of the cut-out switch, thereby shorting the resistor. Continued movement of the rod in a given direction subsequently causes the bridge borne contacts to move away from the stationary contacts, thereby opening the circuit through the resistors.
