How would one go about selecting an appropriate relay to run 120VAC circuit with a 12v automotive switch? I will be running shop lights, Audio equipment, TV, PC, venting fan, etc. Basically, I want to build a DIY control panel similar to what you might find in a Sci-Fi spaceship and have it control everything in my project room/hobby room. Attached is a pic of my inspiration. That control panel incorporates 4 Arduino's, but I am happy just using good old fashioned switched.
