Manual Transfer Switch

A manual transfer switch (MTS) is an electrical device used to switch a power source from the utility grid to a backup power source, such as a generator. It allows users to safely change the power supply to ensure that essential electrical loads continue to receive power during outages or when the main power source is unavailable. As the name suggests, a manual transfer switch requires the user to physically operate the switch to change the power source. This typically involves turning off the main power supply, selecting the generator as the power source, and then turning on the loads you want to power.
