Providing and fixing Gang Operated Gang Switches used to perform Make and Break operation in a sequential way by rotating the switch to different positions to Increase capacity of circuits by ganging in serial or parallel operations for different circuit capacity are used to connect two different circuits from one source. These are used to operate two different circuits with different number of inputs and outputs (potential free contacts) are used to connect two different circuits from two different sources with two different operating voltages or any other incompatible lines. All contacts by default are “Break Before Make” (BBM) type to avoid overlapping of different circuits. However, for overlapping changeover contacts. “Make Before Break” (MBB) type are offered against specific requirements.
