Frequently Asked Questions

Changeover switches are used to safely transfer a load between two power sources – commonly mains and a backup generator – preventing both sources from being connected simultaneously.

Manual changeover switches require an operator to physically switch between sources, while automatic changeover switches detect mains failure and switch to backup power without manual intervention.

Without a changeover switch, there’s a risk of backfeeding the grid from a generator, which is dangerous for utility workers and can damage equipment – a changeover switch prevents this by ensuring only one source is connected at a time.

Changeover switches are available across a range of current ratings – let us know your load requirements and we’ll help match the right model.
