Working of a dual control switch =>
============================
The last common switch to mention is a Dual control switch , but with a center off position. This is commonly used for Hand Off Automatic operation of machines, or Forward Reverse control. In this style switch there are three possible handle positions. In position 1, Line is connected to output A. In position 2, Line is disconnected from both outputs. And in position 3, Line is connected to output B. This setup guarantees that Output A and B are not simultaneously energized, even for a moment, and allows a fully deenergized state for any loads.
