RE: [PSUBS-MAILIST] water proof switches

RAY, ARE YOU REALLY GOING TO BUILD A SUB AFTER ALL THIS TIME BUILDING
THE SITE? That would be momentous news!

Check out West Marine, I think you'll find splash-proof switches there.
Or places like McMaster have things like sealed switches, and toggle
switches with optional rubber boots.

Subject: [PSUBS-MAILIST] water proof switches

Ok,

Another basic parts question. I am designing a
semi-dry ambient. How do I keep electrical switches
dry? For that matter how do I keep the electrics dry?

I can envision running the electrics into sealed
compensated boxes to keep salt water away from bus
bars, barrier strips and fuses. 

How about switches? I can mount them on the front
sides of the sealed boxes to keep the terminals away
from water. How do I keep water from invading through
the front of switches? Can I use gas proof switches?
Are they sealed? Or just designed not to spark?

So far the only real thought I had was to mount push
button switches on a plate then cover with a rubber
membrane. To active a push button, press on the
membrane over the switch and press it through the
rubber.

Displays are easy. I can mount them inside sealed
boxes behind plexiglass.

Regards,
Ray
