Abstract
A linear operating mechanism is provided for operating one or more electrical switches or interrupters, the mechanism selectively closing the switch via movement of a switch operating member and immediately thereafter being capable of opening the switch as required. The operating mechanism includes a carriage that is movable over a linear path to charge an opening spring and a closing spring. The switch operating member is movable along an axis parallel to or coincident with the path of the carriage. The opening spring and the closing springs are disposed about a common axis parallel to the movement of the carriage and the switch operating member. A first latch arrangement is provided for preventing switch-closing movement of the switch operating member when the switch is open and the first latch arrangement is engaged. A second latch arrangement is provided for preventing movement of the carriage opposite to the direction of charging movement after the springs are charged and when the second latch arrangement is engaged. The latch arrangements each include a gapped, latch ring that cooperates with a latch member that is received within the gap of the latch ring. The carriage and t…
