The connection to water is essential but indirect. One button per device. This is default position, which is extended. The device is common in retail establishments; to further clarify, it would be uncommon in a residence.So a commercial use item, still in service today. Has something kind of to do with water. Are there multiple of these buttons? And are we looking at the furthest depressed or extended position of this one?
And would we find this in a retail establishment?
