This was just what we needed. We live in Minnesota and our furnace has a little light switch on the side that turns it on and off. twice in a year the kids managed to bump it and turn it off in the middle of the winter when it was below zero outside. It was super easy to install, just 2 screws that were already there holding the cover plate on, and now, it can't be turned off by accident anymore!
