A Three Phase LT (Low Tension) Changeover Switch is an electrical device used to manually or automatically switch a three-phase low voltage (usually 415V) electrical load between two power sources. It ensures a safe and reliable transfer of power, typically between the utility mains and an alternate source such as a generator or an inverter, without causing backfeed or power interruption.

A Single Phase Changeover Switch is an electrical switching device designed to manually or automatically switch the power supply of a single-phase circuit between two sources. Typically used to select between the main utility supply and an alternate power source such as a generator or inverter, it ensures uninterrupted power supply by allowing quick switching.

An onload changeover switch is a type of electrical switch that allows for the transfer of power between two sources, such as a main utility and a backup generator, without interrupting the connected load. It enables a seamless transition by switching the electrical load from one source to another while both are under power, ensuring continuous operation for critical applications like hospitals, businesses, and industrial facilities.
