A Change Over Switch is required when an external source of power (eg. Generator or Solar System) intends to supply a home or office when the main supply is interrupted (Eskom).

How it Works:

The Change Over Switch is “wired” into the Distribution Board of the building, specific circuits are Isolated (for example the computer room/server is supplied external power).These Switches also allows for a safe means to change from Eskom supply ,to a supply from a Generator or Solar System and can be manual or automatic (ATS-Automatic Transfer Switch).

They also act as a maintenance switch on Solar Systems, if the Inverter requires repair or the batteries are faulty the switch is used to bypass the System while repairs are carried out.


The main types of Change Over Switches are the Rail Mounted (installed inside a DB) or a Rotary (Tumbler) switch (External).
