FAQs:
- Can I use any switch to replace the blue switches? The Themis is hot-swappable with most 3-pin mechanical switches (specifically compatible with Outemu-style sockets), giving you the freedom to switch to silent reds or tactile browns later.
- Does the software work on Mac? The customization software is primarily designed for Windows. While the keyboard works as a plug-and-play device on Mac, advanced macro mapping should be configured on a PC first.
- How loud are the blue switches? Blue switches are known for their distinct “click” sound and tactile bump. They provide great feedback for typing, but they are audible, which makes them satisfying for solo studio work or home offices.
- Is the cable long enough for a large desk? Yes, the included braided Type-C cable is standard length and highly durable, ensuring it can reach your PC tower easily while resisting tangles and wear.
