Jens,The reed switches could be potted easily with epoxy and Cat5 cable would supply 7 locations plus ground. I can't say whether a reed-switch is any more attractive than any other solution, although your LM3914 solution looks pretty compact and simple. I may have missed the discussion, but what is the solution to waterproofing the potentiometer? Or is that where the flat unit Alan found comes in?

Jim Using reed switches would require to enclose them inside non-magnetic pressure vessel(s), and use a magnet on the outside that was strong enough to throw them over. Furthermore, to individually connect, let say, 9 reed switches to their dedicated LED would require a minimum of 10 connectors, i.e. 9 signal paths plus a common ground. Best regards, Jens Laland
