Dummy needs Help!
I am trying to connect two LED 12 vdc lights to come on at intervals on a 3 position rotary switch. . . Position 1 = Off. . . Position 2 = One light comes on. . . Position 3 = Both lights come on. . . This doesn't seem too hard except that in Position 2, where only one of the two lights are suppose to light, the power back feeds to the second light through the wiring connected to Position 3 "where both lights are wired together." I have considered using a diode to block the travel of the (12 vdc) voltage in one direction, but I don't know what size diode to get or if size even matters since I am only using 4 to 8 LED 12vdc lights here. I have also considered using a very small 12 vdc relay here, but that seems like a lot of unnecessary work and consumes a little more power and space than I want. Does anybody have any ideas that will help?? Thanks. . .
