Based on "jacwjames" vendor part number and your picture, the switch may be made by Oslo Switch. See the attached PDF.
Oslo Switch appears to be a non-retail outfit. In the past I've been able to get a replacement part from other manufacturers by calling and asking for a sample. They may be willing to send you an LED sample, instead.
Here's
a link to a company purporting to distribute Oslo Switch products.
Eaton switch also makes a
similar-appearing part.
I could not find any retail replacements without the "I-O" markings, with the slightly-rectangular flange and the two square illuminator windows in the green cap. I find that Google's "Images" view is a help with trying to find parts like these, although this time I struck out.
Here's a
search I ran at Digi-Key.
If you could pull the switch and look for markings, it should help with the search.
Monaco may not have information beyond what "jacwjames" has given, but it probably wouldn't hurt to call them.
