Push buttons

I often have those days when you walk around and don't know what to photograph for the blip. Flowering is so obvious, but that is nice, but not always. So you seek and seek and seek.
The cellar, the attic, the stable everything is turned upside down to find that thing that you think is worth taking a picture of. Everyday things that everyone recognizes or of course cannot identify. Everything is fine as long as it gives you the satisfaction you seek. Sometimes you don't like it and you post something that you just don't like very much.
Today was such a day, but I found something that you often use somewhere every day. Push buttons. What are they not sitting on? The washing machine, dryer, dishwasher, etc.
