Two-Way Centre-Off Changeover Switch
Two-Way Centre-Off Changeover Switch
The Axiom Two-Way Centre-Off Changeover Switch is a manually operated switch that transfers the power source from the main supply to a generator supply and vice versa, with a defined centre-off position so both sources are never connected at once. It is frequently used to distribute low-voltage power circuits across industries and residences.
Used wherever a constant power source is required — homes, hospitals and factories — the switch is physically turned to change the supply. Double-break contacts engineered for precision and reliability, silver-cadmium-oxide contact tips that enhance conductivity and extend switch life, and snap-on DIN-rail mounting integrate it seamlessly into electrical systems, all within a compact footprint that makes no performance compromise.

Frequently asked questions
It switches a load between two sources (e.g. mains and generator) with a centre-off position so both can never be live together.
Yes. The centre-off interlock ensures the two sources are isolated from each other during switching.
