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.
