My switch says in full text Continental Wirt where Wirt is in kind of logo style. This is at the side opposite to that of the rating text mentioned earlier.

Yup, but if you look closely, you'll see the little cW logo, with the W
having like wings or something. That was my clue, we've got the same
switches. CW is a huge switch manufacturer, but maybe the logo changed a
bit over the decades.
