Sylvania Sa155 In-Wall 60 Min Dig Timer

I've got a basement shop with super bright lights, and they're all on the same switch at the top of the stairs. I put in some of these switches in sections. of my shop so I can turn those areas on and off. Now, the stair light switch turns on the whole basement, but only after I hit the button does that area light up. When I flip off the stair switch, all these switches reset to off. I don't have the whole place overlit all day anymore, and it saves a ton of electricity without having to rewire the whole basement. I like this better than motion detectors, but I do use those in smart spots, like by the shop sink.
