Keycaps are plastic caps that cover the keys on a keyboard, primarily used to protect the keys and provide a clear tactile feel and feedback. In mechanical keyboards, keycaps are typically paired with specific switches to form a complete key assembly. Because different switches and key layouts require different keycaps, not all keyboards can use the same keycaps.
For example, keycaps for Cherry MX switches and their derivatives are not fully compatible because their switch sizes and actuation point positions differ. This means that even if two keyboards use the same switch type, the keycaps may not be interchangeable.
Furthermore, different keyboard brands and models have their own keycap compatibility requirements. Some custom keyboards may use special keycaps or layouts that are incompatible with other brands. For example, some high-end keyboards may use non-standard layouts, making universal keycaps unusable.
There are also special keycap shapes and sizes that may not fit the key structure of some keyboards. For instance, some keyboards have unique keycap grooves or protrusions designed to accommodate specific keycap shapes, further limiting the applicability of universal keycaps.
Therefore, we can conclude that not all keyboards can use the same keycaps. When choosing new keycaps or a keyboard, you should carefully check the product specifications and compatibility to ensure your keyboard works properly and provides you with the best typing experience. Different keyboard manufacturers may have different keycap compatibility standards, so be sure to confirm their compatibility with your current keyboard when purchasing or replacing keycaps.
