Dual voltage switch, off .5v on 4.5v? Answered
I have run into a bit of a problem, the original controller has burnt out for my light controller and i cant find a replacement, but i was able to while it was working find out how much voltage it needs to run. To the light controller is 12Volts, It requires .5 volts @ 1amp while the system is in the ready phase and when i press the switch it jumps on 4.5volts @ 1amp and the lights turn on.
Ideas i had run a crossed was:
Running .5 volts straight to the control and having a switch supply the remaining 4.0 volts but i believe that would double the amperage.
Using a relay but i'm not that electrical savvy.
Any help would be great.
