In this video, Mike from The Geek Pub shows us how to replace a light switch. Sometimes light switches just fail, and the repair bill from an electrician can be costly! Follow along in this video and we'll show you how to replace your own light switch. NOTICE: This project involves working with electricity, which can be dangerous and even lethal. If you're not sure of your abilities, call an electrician. You assume all risks. UPDATE: Originally I planned to make a whole channel of DIY Home Improvement videos, but it turns out I just don't have enough time. So I moved them here to DIY playlist to preserve them, and deleted the old channel.
