FAQ

Changeover Switches (Manual & Motorized) questions

What is the difference between a changeover switch and an ATS?

A changeover switch moves the load between two sources when an operator or external signal tells it to. An ATS adds a controller that senses supply failure and transfers on its own.

Do I need a 4P changeover switch?

Use 4P when the neutral must be switched between sources, for example mains to generator. Use 3P where the neutral is solidly common to both supplies.

Do you ship outside Turkey?

Yes. Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock, and we quote project quantities on request.
