Re: Where can I get a 12V timer switch?
I agree. It's a spring timer and contacts. Having a lower voltage only means you've got extra margin on the insulation. I think if there's any issue its using the switch in a humid marine environment where it's internals may corrode.
A spring with contacts. That makes sense.
The second part you mention, that you have an extra margin, makes me think otherwise though. It takes a lot more copper to transmit amps without heat than it does at 120V. That's why boat cables are so big. If it's rated for 20A at 120V it may not take 20A at 12V without melting, right?
It's late, I'm not sure I have that last bit right. Might have to run it by Ohm's law after coffee in the morning and see how it stands up to the light of day...
I have a sauna on my boat, therefore I win.
