The problem with.
The metal dome switches are formed pieces of stainless steel that when compressed give the user a crisp positive tactile feedback.
Mechanical keyboards are also much more durable than rubber dome keyboards.
They have a simple structure consisting of a rubber dome that once pressed completes the circuit on the keyboard s printed circuit board pcb below.
The feel of a keyboard is strongly determined by its switch technology.
The membrane or rubber dome keyboards rely on rubber domes to provide feedback unlike the spring and metal contacts in a mechanical keyboard.
If you are willing to spend a bit more money you may be able to find a more customizable rubber dome keyboard.
