I just stumbled into this website.
More or less detailed copies of classic designs can be seen commonly, usually featuring 12 push buttons in a circle. This one seems to have a more realistic imitation of a rotary dial. Has anybody seen it before? They also advertise a classic ringer.
That would be interesting if they are manufacturing rotary dials. it'd be nice to see the technology behind them.
It appears to me the finger stop swivels when dialing a number is finished. The dial might have a rotary encoder, and a micro controller does the rest.
Still no real dial, but a different approach from the usual buttons.
These have been around for quite a while. Finger stop 'clicks' as the number dialled reaches it.
Nothing to do with the GPO as we know and love it. :)
