Picking up a project that has been put down for 6 months - has
anybody got experience of manufacturing their own ATU
switches out of brass, either as knife switches or else as
ginormous banana plugs which then engage axially with
a sliding action?

I have conceived of a design for an experimental ATU that
allows changes of configuration (including the safety earthing
when not in use) using only 8 single-pole single throw switches,
into the most common configurations.

(I may have mentioned this before in this NG, sorry if so and
thus inducing ennui in my loyal-but-paranoid fan-club of CB types
who seem to hang on my every word)
