Re: [PSUBS-MAILIST] Waterproof controls

Doug Jackson,
  If you were imagining a 1 ATM submersible then perhaps you could forgo 
having buttons through the acrylic dash altogether.  A 1 ATM submersible 
usually only needs splash protection from water, and pressure protection 
when flooding the hull, either for escape or routine locking out.  If you 
have the front panel of the dash removable, then hinge it for easy acces to 
the buttons under normal conditions and latch the panel down air tight when 
flooding the hull.

  That would be of no use to an ambient submersible, as it stops you from 
using the components while the cockpit is pressurized, except for a GPS or 
radio, which are only used at the surface anyway.

  With two people in a 1 ATM submersible, if one person should remain in the 
submersible waiting for the other to return before de-pressurizing the 
cabin, then he would have no access to the sealed components.

  It would be nice if there were a commercially avaiable ball-joint with 
o-ring.  That would allow you to easily hit a group of buttons with only one 
penetration through the 'dash.'


    regards,
      Shin

I was planning on routinely flooding the cabin in order to provide 
additional negative buoyancy and in order to practice emergence escape 
procedures with my partner.  To that end I figured on mounting the fish 
finder and a gps in an enclosed acrylic dash board. It would be nice, but 
not totally necessary to be able to operate a few of the control buttons, 
especially on the gps.  I suppose a mechanical button could be built into 
the acrylic panel but I don't have any simple ideas for that, you?  I don't 
want a CRT just because of the size.
