DIY Vintage Light Switch (Frankenstein Knife Switch)

Parts and Build:

I bought an antique knife switch off eBay as a decoration. When I got it in the mail, I knew I wanted to make it actually work.  But I needed to make it safe.  So I used a solid state relay and a phone changer to wire everything together.  You can watch the process in the video above.  I got everything to fit inside of the light switch box, so I didn’t need to drill into the wall.
