Are you planning to use elastomeric switches ?

I haven't started the design yet. It's scheduled for Jan 2008.
I'll probably try and find out how control pads are designed for
marine applications.
The control pad is not being used at sea but the conditions are
similar but not as harsh.
Elastomeric switches...is that with the rubber buttons? Or is that
like my old calculator with a bubbled rubber *** inside?

I thought about maybe doing a contactless design with opto
interrupters but that might be too extreme.

Look at computer keyboards, or tact switches and boots; in either
case it should be sealed.

Good Luck!
