What is the advantage Varmillo EC switches over Cherry like? With optical ones it is even more or less clear, but why make switches that are no different from classical mechanics?
1 - EC is just a cool technology, completely invisible, almost magic when you do not understand it
2 - diversity is good
3 - to me EC seems better suited to a keyboard as light based systems will likely fail overtime thanks to dust
4 - Varmillo has been making cherry board for a while now, that should allow them to reuse part of their tooling to use those.
5 - experimentation is something that have been lacking in the industry for a long while, so we should welcome new ideas like this one.
the short of it is "why not?" that may bring the EC price down give that only the PCB needs to be redesigned to use this instead of MX style switches, and at worse it is a failure and as a whole we can learn from it.
