Thompson transfer switches make use of a microprocessor based controller and a power contactor switching unit to automatically start a generator and transfer system load to the generator power supply, when a utility supply failure occurs.  Upon restoration of the utility power the automatic transfer switch will revert to the normal power supply. 

These switches are built for residential and light commercial applications.
