    Tips: 2 Pole vs. 3 Pole vs. 4 Pole Knife Switch

    The terms "2 pole," "3 pole," and "4 pole" refer to the number of independent circuits or conductors that a knife switch can control.

    • 2 pole knife switch: A 2 pole knife switch has two separate circuits or conductors that can be controlled independently. It allows for the switching of electrical flow between two different paths. This configuration is commonly used in applications where there is a need to alternate between two power sources or loads.
    • 3 pole knife switch: A 3 pole knife switch has three independent circuits or conductors. It provides an additional circuit compared to a 2 pole switch and offers more versatility in controlling multiple paths. This configuration is often used in complex electrical systems or applications that require the switching of three different power sources or loads.
    • 4 pole knife switch: A 4 pole knife switch has four separate circuits or conductors. It provides even more flexibility and control options compared to 2 pole and 3 pole switches. This configuration is typically used in advanced electrical systems, industrial settings, or applications that involve the switching of four different power sources or loads. 

    The number of poles in a knife switch determines the number of independent circuits it can handle. The choice of the specific configuration depends on the requirements of the electrical system or application at hand.
