I must confess: Your approaches have always fascinated me, and this one I
simply love.

Thanks...

Best regards,

** I made a little sketch for a position sensor using three reed switches and
** 4 wires. When the magnet is over ONE reed switch it lights ONE LED. When
** the  magnet is over TWO reed switches it lights up TWO LED's.
** This is the mid-point between the two positions. This could give a total
** of
**  5 positions.......Full left, half left, center, half right, and full
** right. When  operating the rudder control it would be easy to tell how far
** it has
** turned by  how many and which LED's are lit. It would require a 4 wire
** thru-hull but  wouldn't use any electronics. The reed switches are TINY
** glass
** tubes and would  be easy to seal up as a unit in epoxy. By using single
** strand
** wire there would  be no leakage.
