Questions about Razer Yellow Switch-Set

Unfortunately not in CH layout, the only hotswappable option is the Razer BlackWidow V4 75% which is not available in CH layout.

Razer's interchangeable Yellow Switches are specifically designed to fit hot-swappable mechanical keyboards that support 3-pin switches. They are compatible with most hot-swappable keyboards as they have 3-pin connectors and box-style cross stems that support most keycaps. A concrete example of a compatible keyboard from the Razer range is the Razer BlackWidow V4 75%, which offers a hot-swappable mechanism and thus allows switches such as the Yellow Switches to be changed. The Razer BlackWidow V4 X also uses these yellow switches in the version with linear and quiet switching behaviour. To summarise: These Yellow Switches are suitable for mechanical keyboards with hot-swap function and 3-pin sockets, especially for models such as the Razer BlackWidow V4 75% and BlackWidow V4 X.
