two seprate circuits, one switch?

hello, is it possible to turn on two lights, each on a seperate circuit, together with one switch and still retain the ability to turn them on and off independantly? example: have three switches total, first switch turns on/off light #1, second turns on/off light #2, and third turns on/off both light #1 and light #2 is this possible and if so how can I achive this? thanks

Do you need to ever have both lights on at the same time?  If not, I can do this with 2 switches. 

yes, Im using lights as an example. I need two circuits to function both independently as mentioned and together with one switch. any 12volt experts on here?

If they each have equal priority, I reckon it can be done with 3 push buttons. Problem is, if #1 is on, & #2 is off, does #3 turn both on or both off? If you want #3 to turn both on, that's easy enough with 3 on-off switches & 2 diodes, but for #3 to switch both off requires both #1 & #2 off. If you define what you want (ie, a logic, truth or state table), an answer is possible.

I say "using lights as an example" because the loads could be anything it doesnt matter and I dont want to confuse the question but I'll get into that later. I've many more unusual questions for the forum thats why Im looking for expert advice. first things first. a specialized switch wont work for me. the first two switches need to be in seperate onboard locations and the third via remote control. switch #1 and #2 will generally be off when turning on #3 lets see what we can come up with here! this is just the warm up thread. Im not a 12volt novice by any means but I still have much to learn and Im really thinking out of the box on this project so just wait till you get a load of some of my next questions LOL thanks

no youre "an idiot" couldnt resist.. I tried to squeeze in a good title but the forum doesnt allow enough spaces for one so it is what it is. so what would i am an idiot name this topic? I'll change it if I can and it gets results.

You use lights as an example, but how much current draw are you trying to design this to control?Kevin Pierson
