    I have just begun a project for a device that will be submerged in pool
    water. The depth will be a maximum of ten feet. I am trying to find sealed
    and booted rocker and toggle switches that will withstand continuous
    submersion in pool water with a chlorine content of 2-3 ppm. I am also
    looking for a three-pin panel mount connector that I can use to recharge the
    batteries in the unit when not in use. This connector will be capped when
    the unit is submerged.

    Any ideas?

    Couple the charging power inductively and use either Hall effect or
    photo sensing switches; then you can totally seal the unit.

    The folks who make artificial hearts and similar devices have dealt
    with similar problems.

    Try the company "Birns". They supply connectors for underwater use which
    we have used on ROVs 140-200m depth. Also look for IP68.
