    Frankenstein Light Switch

    From what I was taught about the original knife switches, up was on and down was off. The switch mechanism was heavy compared to switches today. If the switch was bumped, it would fall to the off position. This was much safer than the switch accidentally energizing the circuit. I'm not en electrician or an electrical history buff so I could be wrong.This is a cool project no matter which way faces up. I wish I had a man cave so I could make one of my own.
