What does the term "polarized plug" mean?

The term "polarized plug" refers to a configuration of electrical plugs designed to ensure proper orientation when connecting to an outlet. Specifically, a polarized plug features one prong that is wider than the other. This deliberate design prevents the plug from being inserted into a socket in the wrong orientation, which is crucial for safety. It ensures that the live and neutral wires are connected correctly, reducing the risk of electrical shock or fire hazards that could occur if a device is connected improperly.

By using a polarized plug, the device can effectively manage how power flows, protecting both the user and the appliance. This characteristic is especially important in appliances that contain power switches or circuit components that rely on a specific alignment to function safely and correctly.
