TWO PIN POWER CORD & MAIN LEAD MANUFACTURERS IN UP A two pin plug is a type of electrical plug that is commonly used for small appliances and electronic devices. It consists of two metal pins that are designed to fit into corresponding slots in a power outlet or socket. 2-pin plugs consist of two flat or round pins with one called “hot” or “live” and the other called the “neutral”. When connected to an electric circuit, the current flows from the live pins through the copper conductor and into the device.
