Underwater switches

[Ryerson]

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?

Thanks,

C. Ryerson

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.
