Oh, good, this is public now.
I’ve already commented on the board itself. It incorporates about 90% of the feedback from the XMIT Hall Effect boards. I wouldn’t do analog sense but HaaTa has wanted to do it for ages.
The switch as you see is made by Kaihua. The story here is that at CES in 2018 I brought along a Beam spring sampler and happened to show it to the CEO of Kaihua. The folks at I:C made sure he got some NOS Beam spring switches. That CEO is something of a switch junkie (surprise!) and was optimistic about being able to incorporate something like it into something modern.
With some effort these could be made into retrofits for existing XMIT boards. Though, I can’t promise the actuation would be at the right place.
I do wonder if Kaihua will make Beam spring contact-based switches.
