Welcome to the forum.
That looks like one of the major manufacturers but the logo and/or manufacturers marking is usually on the side without a photo.
If possible please provide a photo of the other side of the switch.
Trying to source a replacement/substitute going just by the electrical specs and one mechanical measurement is time consuming and may not get a suitable result.
Hello,
Welcome to the TechForum!
I have found a similar option on the link below. More information would lead to more options, and I opened up the filters to find stocking options.

Hi mjhowe29,
Unless it’s not important to you, the most important specs for a replacement panel-mount switch are the dimensions of the panel cut-out and the electrical specs. You have provided the latter, but that dimension would be most useful in narrowing down the options.
