One feature of the newer wireless switch I installed to turn on the launch pad (as opposed to the older one I have that turns an LED light on underneath that part of the layout where I have a small FT loop for my grandson set up) is that the center "button" section is actually a removable, smaller rectangle that fits into a magnetic center of the larger switch plate, so that it can be pulled out and operated remotely as long as it's within range of the wireless connector. It comes with a small lanyard so you can walk around the whole playroom and activate the launch pad from anywhere.
