'[PICLIST] [EE}: Re: Need some switch ideas'
2001\04\03@150549 by Lawrence Glaister

Hi Barry,
I made a small underwater flash unit and did not want to have the hassle of
finding a waterproof switch for the on/off switch. Since the enclosure was
plastic, I used a reed switch on the inside and a magnet on the outside
which when placed next to the reed switch turned the flash on. You could
expand this concept to a small keypad if needed. Ceramic magnets dont seem
to have a rusting problem.
