Can I Take a Rubber Dome Keyboard Apart and Switch the Switches with Cherry MX Switches?

No, you cannot directly switch the switches on a rubber dome keyboard with Cherry MX switches. Rubber dome keyboards use a different mechanism for key actuation, relying on rubber domes that collapse to make contact with a circuit board. Cherry MX switches, on the other hand, are mechanical switches that require a different mounting system and actuation method.

If you want to use Cherry MX switches, you would need to build or buy a keyboard designed for mechanical switches, such as a mechanical keyboard kit. Alternatively, you could consider modifying a keyboard with a PCB designed for Cherry MX switches, but this would be a complex task that typically requires soldering and a good understanding of keyboard assembly.

Key Considerations for Modifying Keyboards

While it is theoretically possible to mount Cherry MX switches in a frame and wire them by hand, as explained by Kip Hartwell, achieving a neat swap will be difficult. The issue lies in ensuring that the switch hole in the frame is tight enough to prevent the switch from lifting when you pull the key cap.

Here are some practical steps and considerations for modifying your keyboard for Cherry MX switches:

1. Mounting the Switches

Cherry MX switches need to be mounted on a printed circuit board (PCB). Unlike rubber dome switches, which have traces and thin layers for actuation, Cherry MX switches require a specific mounting system. This typically involves soldering the switches to the PCB directly underneath.

2. Key Caps and Compatibility

You will need key caps that are compatible with Cherry MX switches. There are a variety of key caps available specifically designed for Cherry MX switches, with some offering backlighting capabilities. It is essential to get compatible key caps, as rubber dome keyboards often have unique key shapes and numbers of keys that need to be maintained.

3. Advanced Wiring Techniques

While you can start with just soldering and wiring, for a more professional result, you may decide to dispense with the PCB altogether and run your own wires from the decoder to replicate the original traces on the PCB. This method requires a good understanding of electrical wiring and color coding each row and column to achieve a tighter, flatter, and more serviceable unit.

Conclusion

Modifying a rubber dome keyboard to use Cherry MX switches is a challenging project that requires precision and a good understanding of keyboard construction and electronics. It is not a weekend project and demands careful planning and execution. If you are serious about this modification, it’s best to start by researching thoroughly and possibly consulting with a professional or experienced hobbyist.

Remember, the key to success lies in proper planning, meticulous execution, and a thorough understanding of the components and procedures involved.
