Hey @bsatarnejad, thanks for the contribution!

I'm looking into the CI, as I'm not too sure why it's failing

Edit: Spoke with the team and this behavior is intentional. We'd want to keep the on/off labels consistent with the switch pattern. Let me know if you have any questions, or if there's a specific use case you think that would benefit from this change! I'll close for now, but feel free to respond here 😁

Hi @TylerJDev
Thank you for the clarification. I understand the reasoning for keeping the labels consistent with the ARIA switch pattern.

One consideration I’d like to raise is localization. In multilingual applications, showing the labels only in English (“On/Off”) can feel inconsistent to users in other locales. For example, when the app is set to German, showing “On/Off” in English can feel inconsistent. The semantics would remain the same, but allowing the labels to come from locale files rather than being hardcoded would improve the user experience in localized environments.

Would the team be open to considering translation support, as long as the accessibility and pattern consistency are preserved?
