Need to replace a broken switch on your lamp or want to add a separate control for two lights? This Sara-u double-control switch is just the thing. It's a simple but clever push-button switch. How it works: it has one common connection and two separate outputs. So you can use it to control two different light sources independently (like turning on one bulb or the other, or both) from one button unit. It's perfect for table lamps, floor lamps, or any DIY lighting project. It's made of black plastic, measures about 2.64 x 1.3 inches, and works with standard wiring (for cables smaller than 3.5x6mm). It handles standard household voltage (AC 110-250V) and up to 100W. Installation is straightforward for anyone comfortable with basic wiring. Comes as a single unit with no retail packaging. A handy, inexpensive solution for fixing a lamp or creating custom lighting controls.
