Why Use a Changeover Switch

Changeover switches are critical in systems where power must be manually shifted from one source to another. They let you transfer supply safely and positively, whether you’re switching from main power to a generator or bypassing for maintenance. Their design ensures that you can change sources without risk, and the interlock means there is no possibility of both sources being connected at once.
