Yes, it is a 12 x 12 but as you notice there are two parts. The top is the illumination that also has a filter that goes over it along with different colored lens caps. Pretty sure I can get any switch it's just the rest of it I really need. That's why I was hoping to find the manufacturer. The control panel was produced in Japan and all the other switches that I've replaced on different components for this equipment all originated there. But the logo at the bottom of the switch I cannot seem to find anywhere.
Thank you
