Hi Rick.
Ah! I see what you mean. It sounds like I could
just use a rotary light dimmer switch and epoxy a circular steel
plate to the switch shaft and then seal the whole
thing in a non ferrous pipe with the steel plate
very close to the pipe wall. Then attach a stem to the outside of the pipe
that a knob would turn on and make that
knob with a magnet in it like you said. Are we on
the same page and do you think that would work and the magnet would be strong
enough? You were talking
about neodemium magnets right? If this is correct and I am understanding you correctly,
isn't this the same thing as the motor magnetic clutch's we were discussing
recently?
Any idea where I could get a neodemium magnet? Do
they sell them at home depot? Lol.
Thanks. Bill.

i cant find the site now but the basic idea was
that you epoxy the reed switch to the inside of the caseand then you a knob
on the outside of the case. the underside of the knob has a rare earth
magent iserted in it and a detent ball and spring..if mount two
switches 180 degrees apart that would handle fow/rev. the trick for mag
coupling to thepots is basicaly the same . you mount a disc on the end of
the shaft withtwo mags north north and on the hadle two mags south
south

Hi Rick.
You wrote......"waterproofing electronics
atkins check the
rebreather page for ideas on mags switches. the same
trick would work
using a mag coupler to a potensiometer through an alum or
acrylic
cover plate for your speed control input."
What page (and where at)
were you referring to for me to check the rebreather mag
switches?
Also, where could I find that magnetic
coupler and pot you mentioned that would turn the pot through a cover
plate?
Thanks, Bill.
