Beardsmore calls and I reply.
Oak switches, I recently got some of these (a few months ago). Two types I've seen. The keyboard I have with the ones pictured are so corroded that the springs are disintegrating...
The cross mount ones have patent numbers on them (
https://www.google.com/patents/US3708635). These do not (I believe they are older).
Amusingly, the patent clearly describes the older switches (the newer ones have a bit different housing and are smaller).
It's hard to tell with my corroded ones (I believe these ones are linear), but, the other switches are somewhat tactile (there are some locking versions as well, red sliders).
Some of the switches have dual contacts like some older cherry switches (others do not).
Sorry for the dirty switches, the keyboard must have come out of a swamp (I'm not joking...). Took me about 8 hours to desolder the switches because of all the filth on the pcb...

I don't have a name yet...but since we have the patent, perhaps a bit of progress can be made.
