Changeover Switch Wiring Connection

A changeover switch is a switching arrangement or device that is used to interchange the source of power supply to an electrical load.

There are different types of changeover switches available. Based on the operation it is classified into two types - 1. Manual 2. Automatic. The automatic changeover switch and manual changeover switch built with electrical or electronic circuitry are available in the market as the name of the transfer switch.

Actually, when we talk about changeover switch, it implies the handle type switch. It is the old type switch used in older days. Nowadays automatic switches or electrical circuitry are used. This handle type of changeover switch has metallic paths and handles. The metallic paths of the changeover switch are arranged in such a way that they will connect to each other when we change the position of the handle.

Generally, we can connect two different power sources to the changeover switch and one load. So when we change the position of the handle, the load will disconnect from one source and connect to another source. The handle of the changeover switch can be moved in three positions - source 1, source 2, and off position. When the handle is kept in the off position, the load will disconnect or be isolated from both power sources when we keep the handle in source 1, the load will be connected to source 1 and isolated from source 2. On the other hand, when we kept the handle to the source 2 position, the load will be connected to source 2 and disconnected from source 1.
