Concertina v0.6.0 switches
Detail view of switches mounted in the main and thumb clusters of each half of a Concertina v0.6.0. In this example, I used Matias Quiet Linear (red stem) for the arrow (navigation) clusters and Matias Quiet Click (grey stem) for everything else.
I later replaced the six switches devoted to the pinky finger of the left hand, using Quiet Linear for these as well, and I reused that pattern for Concertina #2. It was an effective solution to reduce strain upon heavy use of the most peripheral keys.
