I have no Universal Switches and therefore only did a review of the files.
You changes are as usual: consistent, clean with comments and unit tests - very good work.
Thank you @david-pace

Left a question and minor comment.

LGTM, Let me know when testing is finished and i'll merge the PR.

Hi @lsiepel, I tested the code well with Universal Switch II. It would be good if someone could test with Universal Switch I as well. But of the testers I know, no one has a first generation device.

On the other hand, Universal Switch I has the very same service API, just the button names are different and I used the ones specified in the official Bosch API and also confirmed with a Python implementation (line 625). So I'm fairly confident that this will work, too.

If you agree that the two sources are enough, we can merge this PR 🚀

As it is a new supported device, there is no risc of regression and we have some milestones before the next stable, hopefully it will get some mileage.
