Gents, can you please **** off.

If you have nothing to contribute to the discussion why join in at all?

My personal theory as to why few commercial morse keys use reed switches
or optical switches is that that users like to able to connect their
morse keys to a wide range of voltages and impedances, especially if you
include traditional valve equipment. Both technologies are intolerant
of excessive voltages or current compared with a pair of solid metal
contacts. I don't think either speed, latency or debouncing are
significant factors or, at least, they could be designed out.



That's another good point, Roger - although reed switches can easily be
connected to a wide range of voltages and impedances.
