you have 2 electrodes.
both are flat metal plates.
both are the size of your thumbnail.
one electrode is positively charged.
the other electrode is uncharged.
the positive charge, can jump through the air,
between the positive terminal, and the uncharged terminal,
without touching !
the 2 terminals only have to be close enough, to each other.
if the uncharged terminal is attached to a spinning wheel,
and the charged terminal is attached to an unmoving wall,
then the charge will induct,
when the wheel moves them close together.
then disconnect, when the wheel moves them appart.
1 rotation of the wheel,
equals 1 connection,
and one disconnection !
the faster the wheel spins,
the more times they connect and disconnect,
per second.
if the wheel is disk shaped, you might fit many electrodes onto its surface.....
if you were "creative" with the wiring job on the wheel,
you could make it so that some electrodes "connect",
in certain patterns.
one of these patterns, might work like a transistor !
another pattern, might even work like an IC circuit......
you will have made a large IC circuit,
which can be designed to conduct FAR MORE voltage and amperage,
than a normal IC circuit.
because it is a mechanical "lego" IC circuit.
and it is as tough as its materials !
'Splain.... with a drawing or two, and I might get your idea a little better.
