The Switch

We are The Switch

Switching power to energy is our mantra. Switching power from the wind and other natural resources into electrical energy is the soul of our business.

The Switch is a leading supplier of megawatt-class permanent magnet generator and full-power converter packages for wind power and other emerging businesses, including solar power and fuel cell applications, variable speed gensets and industrial applications.

Combining a permanent magnet generator with a power converter in a drive train is simple, but nobody integrates them into a totally optimized package the way The Switch does. Our generator and converter package, The Switch Drive™, is tailored to meet each of our customers’ specific requirements and enables them to get more energy from wind power and New Energy sources.

The Switch Drive™ is the soul of every reliable wind turbine.

We aim at being the technology leader for electrical power conversion by switching one turbine at a time wherever energy is gathered.


Our mission is to make sure no potential power from wind gets lost.
