Here's a AND GATE test, can you make a circuit with only 1*any power source+3*SPST switches+3*AND GATEs+1*light and be able to only get the light on when only all the switches are on? If you try and it works can you can post the link in the comments below and say how many try's you did that didn't work + 1, if you give up, can you post how many try's you did?
