Lamp switches can be kind of a pain — either you can't reach them comfortably, they break within a few months, or they just take a lot of force. With an inexpensive touch switch, you can turn any metal lamp on and off just by touching it with your finger.
DIY website Instructables has a guide to hooking a touch switch up to your metal lamp, and it's a pretty cool tweak — not to mention surprisingly useful. The touch switch requires digging into the wiring of the lamp, but it shouldn't be too hard, even if you aren't an electronics guru — the tutorial on Instructables coupled with the touch switch's manual should be more than enough to get you set up.
