Does anyone know of a component - preferably weatherproof - that will power one 12v DC 65w load during the day, and switch to a different 12v 65w load at night, never powering both at once?
The heart of it would be a photocell or any number of light sensors. You want to switch between two 12 VDC 65 Watt loads which is 12 VDC at about 6 Amps so allowing headroom 12 VDC at 10 Amps. Hard to make suggestions without knowing your location but a simple Google of 12 VDC Photocell will bring up a few dozen hits like those on Amazon. Use the output to drive a simple SPDT (Single Pole Double Throw 12 VDC automotive relay. The photocell can be a simple Dawn to Dusk and some versions allow setting how much light when switching takes place. Pretty much a matter of exactly what you want and the exact application.Does anyone know of a component - preferably weatherproof - that will power one 12v DC 65w load during the day, and switch to a different 12v 65w load at night, never powering both at once?
How did you know it was a fountain?Another option, much simpler, would be to have a simple switch to switch on the fountain when you wish to see it, and switch it off the rest of the time.
It was mentioned someplace at one point, earlier during the discussion. I think about the time that it was explained that we were not discussing 220 volt mains power switching. The suggestion that I had initially offered would have been a very simple and easy way to do it if the power were 220 volt mains. 12 volts from a battery system makes it more complex.How did you know it was a fountain?

Thanks as I was wondering, fountain? What fountain?It was mentioned someplace at one point, earlier during the discussion.

I must have missed that meeting!Thanks as I was wondering, fountain? What fountain?
