Hello! I just bought a 1940 colonial in Detroit, mi. Same owner since 1960. The home is basically original other that major systems.
To my question: in the kitchen and in the upstairs bathroom there is a plate with two buttons and a little light panel. One white, one black button. The plate is the same size as a light switch plate. There is no wording or markings on the outside or inside of the panel. Pressing the buttons do nothing anymore. Does anyone know what this used to do?
