The dimmer switches are magnetic and go to a plate that sticks to the wall with double sided tape. The thing I linked is instead a module that gets wired into the circuit and the switch so it knows when the switch is flipped to turn off the lights, but still keeps the circuit powered for the lights. It's battery powered though. Like, if you're going to be wired into the circuit, why have a battery?
