That was my guess because the flat I live in (80s East German) has one just like that.
Living room could mean that there was the idea of a light for a dining table.
Otherwise a power socket outside, on the terrace for example or an outside light?
Garage door opener maybe?
If you really want to find out, I think you’ll need to “play” around with your safety box and that particular switch
