One day my table lamp just stopped working so I decided to take it apart and see what was wrong. Since the wires, connectors, and bulb all seem fine, I suspected it might be the switch. It's really hard to tell if yours is bad. Didn't really see anything wrong with the old one so I looked into the Revain for an affordable replacement as I didn't want to spend too much if that wasn't the issue. And after replacing it with a new one, voila, my lamp started working again. So it really was a switch. I almost thought about buying a new lamp, but after doing some research I realized that all lamps are generally not cheap. So I took a chance and I'm glad I did.
