Abstract

THE PRESENT INVENTION RELATES TO AN IMPROVED MECHANICAL INTERLOCK, DUAL TOGGLING AND/OR THREE POSITION MECHANISM OF AN ELECTRICAL LOAD BREAK SWITCH. THE MECHANISM COMPRISES ROTATING SHAFT MEANS (5), OPERATING HANDLE MEANS (4), SPRING ARM MEANS (13) HAVING A MECHANISM SPRING MEANS (14); A LINK ARRANGEMENT (15), INTERLOCK LINK (09) AND PLURALITY OF OPERATING SHAFT MEANS INCLUDING MAIN SWITCH OPERATING SHAFT MEANS (11) AND EARTH SWITCH OPERATING SHAFT MEANS (12). THE SPRING ARM MEANS (13) IS OPERATIVELY CONNECTED TO THE MAIN SWITCH OPERATING SHAFT MEANS (11) AND EARTH SWITCH OPERATING SHAFT MEANS (12). THE LINK ARRANGEMENT (15) COMPRISES SUBSTANTIALLY A TRIANGULAR SHAPED LINK CONNECTOR AND OTHER LINK CONNECTORS. THE INTERLOCK LINK (09) COMPRISES AT LEAST TWO CONNECTORS WHICH ARE CONNECTED TO OTHER CONNECTOR FORMING SUBSTANTIALLY ‘V’ SHAPE BY MEANS OF HINGE AT ONE END TO FACILITATE THE MOVEMENT OF THE ASSEMBLY.
