Hey @tiloburgey, the switch component that you can currently see on onyx.schwarz is not an onyx component, it is provided by VitePress. Currently we are using VItePress to build or documentation but we will build a new fully onyx-based showcase/documentation in the future.

For placing a light/dark switch in your application, we recommend using the OnyxColorSchemeDialog component. We also offer a OnyxColorSchemeMenuItem component that you can easily place inside the user menu of your nav bar which includes the dialog internally.

If I remember correctly, we do not plan to support custom icons in the OnyxSwitch itself. Maybe @SchwarzIT/onyx-ux can provide some more details here or correct me if I am wrong
