Turn Please
This is a mechnical door bell.
Do not turn the small handle unless you want someone to answer the door. I learnt the hard way.
Surprisingly difficult knowing what to say in an unfamiliar language to a confused soul having just accidentially rung their door bell.
It is only on closer inspection of this photo that I notice the words “Tournez SVP” embossed on the plate; this translates to “turn please”.
